Mount Daniel, Mountain summit in Kittitas County, United States

Mount Daniel is the highest summit on the Cascade Range crest of Alpine Lakes Wilderness in central Washington, and the highest point in King and Kittitas counties. From most vantages it appears as a triple-crowned mass, but five summits can be identified: West Summit (7,960+ ft), Middle Summit (7,959 ft), East Peak (7,899 ft), West Pyramid (7,880+ ft) and Northwest Summit (7,686 ft). Its volcanic rock consists of andesite, dacite and rhyolite inflows, breccia and tuff, with interbedded volcanic sandstone. The largest glacier, Lynch Glacier, descends the northwest slope from 7,800 ft to 6,220 ft into Pea Soup Lake.

The first recorded ascent of Mount Daniel was made in 1925 by a party from The Mountaineers, who climbed via Lynch Glacier. Surveyors may have reached the summit earlier. The standard route today passes Cathedral Rock and Peggy's Pond before a scramble to the top, not the glacier.

The name Mount Daniel was assigned by the United States Board on Geographic Names to the east peak, at 7,899 ft, even though the west summit is higher. The mountain's five summits are counted from the 1965 Mount Daniels 7.5-minute topographic map, and the 1925 Mountaineers party climbed via Lynch Glacier, not the modern standard route.

Reaching the top requires glacier travel experience and proper equipment, since the route crosses snow and ice for much of the way. Late summer generally offers the most stable conditions, though snow can remain on the upper sections well into the season.

Mount Daniel is the highest point in the Middle Fork Snoqualmie River watershed, making it a notable water source for the lowlands to the west. Meltwater from the Lynch Glacier feeds streams that eventually drain into Puget Sound, connecting the high alpine zone to the coast.
