The Oregon High Desert Grotto (or OHDG) is an American caving club, known as a Grotto. It is affiliated with the National Speleological Society.
OHDG is involved with caving and conservation efforts in central Oregon and beyond, including the Oregon Caves National Monument, [1] the Lava Beds National Monument in northern California, [2] and caves in western Idaho and southern Washington. Members of the Grotto have worked with the Department of State Lands and received a participation award from state leaders for their volunteer work. [3] [4] [5] In 2013, the Grotto was recognized by Region 6 of the United States Forest Service for various volunteer hours working with caves and bats. They received the R6 Volunteers and Service and Program Award. [6]
The Oregon High Desert Grotto was first created in 1989 by Dan Best. [7] It lasted only a year before complications terminated the Grotto. [8] In late 1995, the OHDG was reformed by the new founding member Ric Carlson, who was at the time an employee of the United States Forest Service. [9] By 1997, the Grotto had over 30 members, a newsletter publication, and a growing knowledge of caves in the Central Oregon area and beyond. [8] As of 2012, the OHDG continues to find new caves. Grotto member Matt Skeels has found over 100 new caves. [10] [11] Today, the Grotto is actively involved with caving in most of Oregon and the adjacent states. [12] [13] [14] [15] [16]
Members of the Oregon High Desert Grotto understand that caves are a fragile resource. They are dedicated to preserving these special underground spaces. Each year, the group organizes a number exploration trips, study efforts, and preservation projects. The group’s exploration work includes caving adventures, cave surveys, and photographic documentation of cave resources. [17]
While members of the Oregon High Desert Grotto have explored caves all over the western United States, the group’s focus is on Central Oregon. Most of the known caves in Central Oregon are in Deschutes County, the group's home area. The Oregon High Desert Grotto has identified 813 caves in Deschutes County, 660 of these are lava tubes. Of the remaining caves, the majority are also lava-related formations including vertical conduits, fissures, bubbles, and lava molds. Of the 813 caves, there are only 52 that were not created by lava flows. Many of these are rift or fissure caves, some up to 150 feet (46 m) deep. There are also a number of rock shelters, large rock overhangs created by water or wind erosion. These caves occur throughout Central Oregon, usually in rim rock areas. Finally, there are a few talus caves. Talus caves are found in cracks and open spaces between boulders along faults and in rock fall areas. [17]
and mapping of the glacier-fumarole cave system at the summit of Mount Rainier in Washington. [18] Some Central Oregon caves are easy to explore, especially the larger lava tubes. However, other caves require significant planning in order to be explored safely. Many require a strenuous hike just to get to the cave; and while underground, dark spaces and tight passages can be dangerous for anyone who is not prepared. As a result, members of the Oregon High Desert Grotto are careful to bring along the proper equipment for each caving trip. Explorers always wear helmets to protect their heads. Each person brings three sources of light, and members never go caving alone. [17] [19]
Members of the Oregon High Desert Grotto are always careful to protect wildlife. During the winter, grotto members avoid caves with hibernating bats. Waking a bat from hibernation is extremely stressful, and may cause the bat to expend its fat reserves prematurely which can lead to death later that winter or early spring. The group also avoids caves with bat maternity colonies during the summer months. [19] [20]
Over the last few years, the Grotto has been involved in the study and mapping of the Sandy Glacier Caves on Mount Hood in Oregon. [21] [22] [23] Their efforts were recorded by Oregon Field Guide in 2013 and aired on OPB in October of that year. [24]
The Grotto was also involved in the exploration.
The OHDG is an avid participant in conserving and restoring caves since many of the caves have been damaged from increased recreational activities, including rock climbing. [25] [26] [27] The Grotto often partners with the United States Forest Service (USFS) to help manage the caves of the Deschutes National Forest. [12] [28] [29] Cooperation with private owners of caves has also been done. [30] On National Public Lands Day in September 2000, the Grotto participated in the gating of Stookey Ranch Cave. [31] Cleanup trips to caves in the area are common and are synonymous with the caving motto: "Take nothing but pictures, leave nothing but footprints, kill nothing but time." [32] [33] [34] In late 2010, missing lavacicles from Lavacicle Cave were reacquired by Grotto member Eddy Cartaya while working for the USFS. [35] [36] The lavacicles will be used as educational tools at Lava Lands Visitor Center. [37]
The Grotto is involved with caving and conservation efforts beyond its local area of central Oregon. Grotto member Brent McGregor produced a video for the Oregon Caves National Monument promoting safe caving to conserve the off-trail parts of the cave. [1] Other efforts have been done with Lava Beds National Monument in northern California, [38] western Idaho, and Nevada. [13] [14] [15] [16] Ken Siegrist, of the Grotto and former employee of the Bureau of Land Management, has worked to protect many caves, including those of eastern and southern Oregon. [12] Members of the Grotto have also worked in conjunction with the Department of State Lands and received a participation award from State leaders for their volunteer work with the state. [3] [39] Additionally, the Grotto along with land management agencies, has helped collect and discover millipedes, campodeans, arachnids, and the Taracus marchingtoni, some new to science. Neil Marchington has helped discover the Trogloraptor marchingtoni of southwest Oregon. [10] [40] [41] [42]
Deschutes County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the population was 198,253. The county seat is Bend. The county was created in 1916 out of part of Crook County and was named for the Deschutes River, which itself was named by French-Canadian trappers of the early 19th century. It is the political and economic hub of Central Oregon. Deschutes comprises the Bend, Oregon Metropolitan Statistical Area. Deschutes is Oregon's fastest-growing and most recently formed county.
Newberry National Volcanic Monument was designated on November 5, 1990, to protect the area around the Newberry Volcano in the U.S. state of Oregon. The monument was created within the boundaries of the Deschutes National Forest, which is managed by the U.S. Forest Service, and includes 54,822 acres of lakes, lava flows, and geologic features in central Oregon.
Newberry Volcano is a large active shield volcano located about 20 miles (32 km) south of Bend, Oregon, United States, 35 miles (56 km) east of the major crest of the Cascade Range, within the Newberry National Volcanic Monument. Its highest point is Paulina Peak. The largest volcano in the Cascade Volcanic Arc, Newberry has an area of 1,200 square miles (3,100 km2) when its lava flows are taken into account. From north to south, the volcano has a length of 75 miles (121 km), with a width of 27 miles (43 km) and a total volume of approximately 120 cubic miles (500 km3). It was named for the geologist and surgeon John Strong Newberry, who explored central Oregon for the Pacific Railroad Surveys in 1855.
The Three Sisters Wilderness is a wilderness area in the Cascade Range, within the Willamette and Deschutes National Forests in Oregon, United States. It comprises 286,708 acres (1,160.27 km2), making it the second largest wilderness area in Oregon, after the Eagle Cap Wilderness. It was established by the United States Congress in 1964 and is named for the Three Sisters volcanoes. The wilderness boundary encloses the Three Sisters as well as Broken Top, which is southeast of South Sister.
Central Oregon is a geographic region in the U.S. state of Oregon and is traditionally considered to be made up of Deschutes, Jefferson, and Crook counties. Other definitions include larger areas, often encompassing areas to the north towards the Columbia River, eastward towards Burns, or south towards Klamath Falls. These three counties have a combined population of 200,431 as of the 2010 census, with Deschutes the largest of the three counties, having approximately four times the population of the other two counties combined. As of 2015, the most populous city in the region is Bend, with an estimated 87,014 residents. As defined by the three county definition, Central Oregon covers 7,833 square miles (20,290 km2) of land. Central Oregon has had 3 record tourism years beginning in 2012. Over 2.2 million people visited Central Oregon in 2012 and again in 2013.
Diamond Peak is a volcano in Klamath and Lane counties of central Oregon in the United States. It is a shield volcano, though it might also be considered a modest stratocone. Diamond Peak forms part of the Cascade Volcanic Arc, a segment of the Cascade Range in western North America extending from southern British Columbia through Oregon to Northern California. Reaching an elevation of 8,748 feet (2,666 m), the mountain is located near Willamette Pass in the Diamond Peak Wilderness within the Deschutes and Willamette national forests. Surrounded by coniferous forest and visible in the skyline from foothills near Eugene, Diamond Peak offers a few climbing routes and can be scrambled. Diamond Peak is one of Oregon's Matterhorns.
The Deschutes National Forest is a United States National Forest located in parts of Deschutes, Klamath, Lake, and Jefferson counties in central Oregon. It comprises 1.8 million acres (7,300 km2) along the east side of the Cascade Range. In 1908, the Deschutes National Forest was established from parts of the Blue Mountains, Cascade, and Fremont National Forests. In 1911, parts of the Deschutes National Forest were split off to form the Ochoco and Paulina National Forests, and parts of the Cascade and Oregon National Forests were added to the Deschutes. In 1915, the lands of the Paulina National Forest were rejoined to the Deschutes National Forest. A 1993 Forest Service study estimated that the extent of old growth in the forest was 348,100 acres (140,900 ha). Within the boundaries of the Deschutes National Forest is the Newberry National Volcanic Monument, containing cinder cones, lava flows, and lava tubes. The Deschutes National Forest as a whole contains in excess of 250 known caves. The forest also contains five wilderness areas, six National Wild and Scenic Rivers, the Oregon Cascade Recreation Area, and the Metolius Conservation Area. Forest headquarters are located in Bend, Oregon. There are local ranger district offices in Bend, Crescent, and Sisters.
The Oregon high desert is a region of the U.S. state of Oregon located east of the Cascade Range and south of the Blue Mountains, in the central and eastern parts of the state. Divided into a southern region and a northern region, the desert covers most of five Oregon counties and averages 4,000 feet (1,200 m) above sea level. The southwest region is part of the Great Basin and the southeast is the lower Owyhee River watershed. The northern region is part of the Columbia Plateau, where higher levels of rainfall allow the largest industry on private land to be the cultivation of alfalfa and hay. Public land within the region is owned primarily by the Bureau of Land Management, which manages more than 30,000 square miles (78,000 km2) including five rivers designated as Wild and Scenic.
The Oregon Badlands Wilderness is a 29,301-acre (11,858 ha) wilderness area located east of Bend in Deschutes and Crook counties in the U.S. state of Oregon. The wilderness is managed by the Bureau of Land Management as part of the National Landscape Conservation System and was created by the Omnibus Public Land Management Act of 2009, which was signed into law by President Barack Obama on 30 March 2009.
The Horse Lava Tube System is a series of lava tubes within Deschutes County, Oregon, of the United States. The system starts within the Deschutes National Forest on the northern flank of Newberry Volcano and heads north into and near the city of Bend. The system continues north to Redmond and includes the Redmond Caves. The flow diverts into the Redmond Dry Canyon, where the last known segment is known to exist; however, the basalt flow that created the system goes beyond to Crooked River Ranch and terminates just short of the Crooked River Gorge. The lava flow that created the Horse system is also referred to as the Horse Cave lobe and it filled the ancient channel of the Deschutes River which at that time flowed around the east side of Pilot Butte. The Horse Cave lobe is a part of the basalt of Lava Top Butte which also consists of the Arnold Lava Tube System, the Badlands rootless shield, and the Lava Top butte basalt. All have a geologic age around 80,000 years old.
The Arnold Lava Tube System is series of lava tubes in Deschutes County, Oregon, in the United States. It is located several miles southeast of the city of Bend. The system starts in the Deschutes National Forest on the northern flank of Newberry Volcano, heads northeast onto BLM land before finally terminating on private property near Horse Ridge. The system acted as a conduit for the lavas from Lava Top Butte that later fed the Badlands rootless shield. The lava flow that created the Arnold system is also referred to as the basalt of Lava Top Butte and is related to the Horse Cave lobe which is a lava flow that created the Horse Lava Tube System. The lava flows of Lava Top Butte, the Badlands, the Horse system, and the Arnold system all have a geologic age around 80,000 years old.
The Redmond Caves are a group of six lava tubes in Deschutes County, Oregon, United States. The caves are located in the city of Redmond and are jointly managed by the city and the Bureau of Land Management (BLM). Five of the caves are in the Redmond Caves Park and have been known locally for over 100 years. The caves are part of the Horse Lava Tube System and the farthest northern extent of the system. The lava flow that created both the Horse system and the Redmond Caves continued into the Redmond Dry Canyon and terminated near Crooked River Ranch. The caves have a geologic age of about 80,000 years.
Skeleton Cave is a lava tube within Deschutes County, Oregon, of the United States. The cave is within Deschutes National Forest and is located on the northern flank of Newberry Volcano near the city of Bend. The cave is between 75,000 and 400,000 years old.
Derrick Cave is a lava tube located in the remote northwest corner of Lake County, Oregon. The cave is approximately 1,200 feet (370 m) long. It is up to 80 feet (24 m) wide and 46 feet (14 m) high in places. It was named in honor of H.E. Derrick, a pioneer rancher with a homestead 3 miles (4.8 km) southeast of the cave. The land around the cave is managed by the United States Department of Interior, Bureau of Land Management. Derrick Cave is open to the public year-round; however, camping is no longer permitted in the cave.
The Sandy Glacier Caves are a system of glacier caves within the ice of Sandy Glacier on Mount Hood, Oregon. They are thought to be the largest glacier caves in the lower 48 states of the United States. Surveys done in 2011 and 2012 have measured the system at over 1 mile in length or about 7,000 feet. The caves formed from internal glacial melting at what are the headwaters of the Muddy Fork river. As melting continues, the caves grow larger with their entrances melting their way up the glacier's slope. Eventually it is predicted the caves will be completely gone within 7 to 10 years once the interior melting has reached the surface of the glacier.
Boyd Cave is a lava tube within Deschutes County, Oregon, of the United States. The cave is within Deschutes National Forest and is located on the northern flank of Newberry Volcano near the city of Bend.
Skylight Cave is a lava tube within Deschutes County, Oregon, of the United States. The cave is within Deschutes National Forest and is located east of Belknap Crater about nine miles northwest of the city of Sisters. Skylight Cave is closed to visitation from September 15 to April 30 because of hibernating Townsend's big-eared bats.
Taracus marchingtoni is a genus of harvestman found in the lava caves of semi-arid and arid regions of central Oregon. It belongs to the family Taracidae and was first collected by Jean and Wilton Ivie in 1965 in Lava River Cave but not identified as a new species until collected by Neil Marchington of the Oregon High Desert Grotto in 2008. Its range is suspected to be the surrounding areas of Newberry Volcano. It has enlarged but thin chelicerae, typically equal to or longer than the entire length of the body, and in small-bodied males nearly three times as long. The harvestman is troglobiotic and has a predominantly white abdomen, black chelicerae, and highly reduced eye size. T. marchingtoni has been observed feeding on small troglophilic millipedes identified as Plumatyla humerosa of the Conotylidae family.
Plumatyla humerosa is a millipede species found in mines, as well as lava tube and limestone caves of northern California and south-central Oregon. It belongs to the family Conotylidae. The millipede is likely a troglophile with a white carapace and observed in lava caves though it may inhabit crevices as well. P. humerosa is observed frequenting areas with mold or bat feces on the cave floors. Taracus marchingtoni has been observed feeding on P. humerosa within cave habitat.
