Alta Mountain is located northeast of Snoqualmie Pass in the Alpine Lakes Wilderness. Alta can be seen from Interstate 90 near Hyak as it is situtated at the north end of Gold Creek Valley between Rampart Ridge and Chikamin Peak. Alta stands directly across this valley from Kendall Peak. Alta is slightly on the east side of the Cascade Crest spine, so precipitation from Alta drains into the Yakima River, which in turn drains into the Columbia River.
Alta Mountain is shown on maps with a 6151 ft elevation, but the true summit is a little bit east with a 6240+ elevation. There is a 12 mile round-trip trail to to reach the summit. From the Lake Kachess campground, drive the signed road to Rachel Lake Trail. Hike the trail to Rachel Lake, then before reaching Lila Lake follow a climber's path up the ridge to the summit. Approximately 3300 ft gain and 4 to 5 hour dayhike, all walk-up except Class 2 at the summit. Camping at Rampart Lakes makes for a nice overnight trip.
Prominence: 520 feet.
