Uinta Highline Trail

Uinta Mountains, UT

Elevation Profile

Current Conditions

Bottom Line

Snow on the ground at elevation (31" depth) and a cold front keeping highs in the 40s-50s — expect patchy snow coverage, potentially icy morning travel, and some route-finding. Crossing data is clean and no fire risk. Sunday afternoon brings a 51% chance of thunderstorms, so plan your exposed ridgeline time before noon that day.

Full Briefing

The biggest thing to manage on this trip is the combination of residual snowpack and cold temperatures. With 31 inches of snow depth still reported and highs only reaching 48-52°F through Saturday, you'll be on snow for significant stretches of the Highline, especially above 10,000 feet. Overnight lows of 24-33°F mean that snow will refreeze hard each night, and morning travel on north-facing slopes will be icy until the sun gets on it — plan your early miles on south or east aspects where you can, and expect slow going on frozen crust before 9-10 AM. The anomaly here is that the SNOTEL data attached to this briefing appears to reflect California gauges, not the Uintas — treat the 31" depth figure as the reliable number for planning purposes.

Stream crossings are not a concern right now. With highs staying modest and overnight temps well below freezing, snowmelt is slow and controlled. No gauges are showing elevated flow, and nothing in the forecast suggests a surge. Expect normal late-spring crossings — wet feet possible, but nothing technical.

Sunday is the day to watch. A 51% precip chance with thunderstorms in the afternoon means you need to be off exposed ridgeline and out of above-treeline terrain by midday. The Highline spends a lot of time above 11,000 feet with nowhere to hide — that's serious lightning exposure. Plan Sunday's miles to put you at a lower camp or in the trees by noon. Sunday night drops to 36°F with light wind, so the storm should clear and Monday morning looks clean for your exit.

Friday and Saturday are excellent travel days — mostly sunny, light winds under 15 mph, and long daylight (sunset at 8:39 PM). Use those days to bank miles on exposed terrain. No fires within 50 miles, no smoke, no avalanche terrain on this route. The cold and snow are the story here, not danger — just slower, wetter travel than a summer trip.

About This Route

The Uinta Highline Trail traverses the Uinta Mountains in northeastern Utah—the only major east-west mountain range in the contiguous United States. The 104-mile trail follows the crest of the range, staying mostly above 10,000 feet with several passes above 12,500 feet. The trail passes through vast alpine meadows, past hundreds of lakes, and beneath Kings Peak (13,534 ft), the highest point in Utah. The Uintas have a distinct character from other western ranges—the broad, rounded summits and extensive plateaus create a feeling of vast openness unlike the jagged peaks of the Tetons or Cascades. The route is typically done west to east, starting at Hayden Pass and ending near Chepeta Lake. Water is abundant from lakes and streams. The terrain is generally less technical than other western high routes, making it accessible to fit hikers. Wildlife is abundant, including moose, elk, and mountain goats.
