Ice Lakes and Island Lake: The 3,350 m Basin That Ruins Every Other Colorado Lakeeasytravelpost #Ic
#easytravelpost Ice Lakes Basin above Silverton is a 17 km out-and-back, 1,070 m gain, trailhead at 2,950 m off FR 585 (high-clearance recommended past the summer parking lot). I started at 6 a.m. from the upper lot (free, no permit, no pass—San Juan National Forest, no day-use fee), walked through spruce then into the open basin where Lower Ice Lake appears at 3,250 m and Upper Ice Lake (3,350 m) sits under Mount Silex. Island Lake is 20 min west on the moraine, colder, less crowded, the better campsite if you overnight (dispersed, no permit, pack out everything, bear-proof hang or canister).
The water is the color—glacial flour + depth = electric cobalt. I filtered 3 L at Lower Ice and still drank the upper lake untreated once (don't, giardia in San Juans is documented). Wildflowers peak late July; by mid-August the basin browns. FR 585 is a washboard nightmare in a sedan—I saw a Corolla high-center at the first water bar.
Mistake: I came August 5 after a warm week and postholed knee-deep on the Silex face approach to the upper lake—July or early Aug only, or bring spikes. Another: I wore a softshell and the 3,350 m wind at 14:00 dropped to 4°C; down jacket in the pack even in summer. Would you day-hike Ice Lakes Basin, or backpack in and sleep at Island Lake for the 6 a.m. reflection?
