Angeline Lake is a freshwater lake located on the northern slope of Iron Cap Mountain between Otter Lake, Azure Lake and Big Heart Lake, in King County, Washington. [4] Self-issued Alpine Lake Wilderness permit required for transit within the Big Snow Mountain area. [5] West Fork Foss River exits Angeline Lake into a canyon that produces Angeline Falls downstream from Chetwoot Lake to Delta Lake. Because Angeline Lake is at the heart of the Alpine Lakes Wilderness, the lake is a popular area for hiking, swimming, and fishing golden trout, rainbow trout, and cutthroat trout. [2]

Outlet

Angeline Lake has a low watershed to surface area ratio with low flushing rates. [6] [7] The lake has a subterranean outlet. [8] The top land of the outlet channel is blocked by a large landslide. As a consequence, the water exiting the lake percolates in through the landslide and emerges about 1,000 feet downstream from the lake. At this surfacing point, the stream cascades steeply down the hillside over cliffs that line the south side of the Delta Lake basin, forming Angeline Falls, spreading out to 80-100 feet in width and pitching down nearly vertically 424 feet to the talus slopes below. [9] After the pool of the waterfall, the creek cascades for a short distance before again being absorbed into the rocky slope and receding entirely underground again, emerging approximately 600 vertical feet further down at the south end of Delta Lake.

Geography

Angeline Lake is nestled in a long structural benchland with relatively level or gently inclined land bounded by the distinctly steeper slopes of Atrium Peak above and between Angeline and Big Heart Lake. [10] The lake is located in a prominent valley along the western skirt of the Mount Daniel area in connection with the North-Middle Forks Snoqualmie mountain grouping area. [11] The valley follows patterns of geomorphology typical of the Northern Cascade Mountains of the Pacific Mountain System with a bedrock composed of pyrrhotite and pyrite found in thin seams 804 metres (2,638 ft) wide at a depth of 304 metres (997 ft) below the surface. [12] The host rock in this area is greensand from the Lopingian epoch 260 to 250 million years ago.

Climate

Angeline lake is within a hemiboreal climate. [13] The average temperature is 0°C. The warmest month is August, with an average temperature of 13°C, and the coldest month is January, at an average of −10 °C. [14] The average rainfall is 1,989 millimeters per year. The wettest month is January, with 248 millimeters of rain, and the least in August, with 41 millimeters of rain. [15]

Access

Access to Angeline Lake is through West Fork Foss Lakes Trail #1064 off Forest Service road 6835 a side road of Foss River Road (Forest Service Road #68), which exits U.S. Highway 2. The trail borders Trout Lake, Lake Malachite, Copper Lake and Little Heart Lake before ending on campsites along Atrium Peak, the ridge between Big Heart Lake and Angeline Lake to the East. [16] The output of Big Heart Lake is approximately a mile from the output of Angeline Lake. [17] Self-issued Alpine Lake Wilderness permit required for transit within the Necklace Valley area. [18]

Mount Adams, known by some Native American tribes as Pahto or Klickitat, is a potentially active stratovolcano in the Cascade Range. Although Adams has not erupted in more than 1,000 years, it is not considered extinct. It is the second-highest mountain in Washington, after Mount Rainier.

<span class="mw-page-title-main">Alpine Lakes Wilderness</span> Wilderness area in Washington (state)

The Alpine Lakes Wilderness is a large wilderness area spanning the Central Cascades of Washington state in the United States. The wilderness is located in parts of Wenatchee National Forest and Snoqualmie National Forest, and is approximately bounded by Interstate 90 and Snoqualmie Pass to the south and U.S. Route 2 and Stevens Pass to the north. The Alpine Lakes is the largest wilderness area near the population centers of Puget Sound, counted at 414,161 acres (167,605 ha) following the 2014 expansion.

The valley of the West Fork Foss River contains a fair amount of waterfalls. The river heads in a series of large lakes: Big Heart Lake, Angeline Lake, and Otter Lake- which form spectacular waterfalls as they plunge down to Delta Lake. On the valley walls downstream of Delta Lake, are found even more waterfalls.

The Foss River is a stream in the U.S. state of Washington. It has two main forks, the East Fork Foss River and the West Fork Foss River. The main stem is formed by the confluence of the two forks. The river and its forks rise near in the Alpine Lakes Wilderness area of Mount Baker-Snoqualmie National Forest in the Cascade Mountains and flows generally north, joining the Tye River to form the South Fork Skykomish River. The Foss River's waters eventually empty into Puget Sound near Everett via the Skykomish River and Snohomish River.

Big Heart Lake is the most remote and highest-elevation on-trail lake in the West Fork Foss River system. It is a 14.6-mile (23.5 km) round-trip hike from the trailhead, just off of the Foss River Road. The lake is located at the eastern base of Camp Robber Peak in the Alpine Lakes Wilderness Area, within King County, Washington.
