Berthoud Pass Backcountry

Clean bulletin from CAIC — Moderate across all elevations, zero identified problems. That's genuinely good news for late April. The caveat is that you're touring into an active storm cycle, not settled conditions. Snow showers are running 79-84% probability through Tuesday with W winds 15-25 mph, which means east-facing terrain is loading continuously. No wind slab problem is currently identified, but that's today's bulletin. By Tuesday afternoon, fresh wind slabs on east and northeast aspects above treeline will be worth probing before committing.

Temperatures stay well below freezing through the trip — highs of 25-31°F, lows in the 18-21°F range — so wet loose is off the table entirely. No afternoon solar concern, no rain-on-snow threat. The snowpack at elevation is holding 35 inches, and the cold temps mean new snow is bonding onto a frozen surface rather than a wet, reactive one. That's a favorable setup for storm slab stability, but give new snow 12-24 hours to bond before you ski steep lines off fresh wind-loaded rolls.

The SNOTEL data here is a bit of a mismatch — the nearest stations with meaningful depth readings (Long Lake at 840 ft showing 92 inches, Annie Springs at 6021 ft showing 12 inches) don't map cleanly to Berthoud Pass terrain at 11,300+ ft. Use the 35-inch local snowpack figure as your reference and treat it as a solid spring base. The falling trend at Long Lake likely reflects low-elevation melt, not relevant to your terrain.

Timing-wise: start early each day to evaluate new snow loading before wind has had all morning to work on east aspects. Wednesday lightens up to 52% precip probability and winds drop to 15-18 mph — that's your best weather window of the trip for bigger objectives. Tuesday is the most active day; consider lower-angle terrain or sheltered north-facing glades if the storm is still cranking when you skin up. You've got nearly 14 hours of daylight, so no pressure on start times, but the best snow quality will be before solar softening gets going on south and west aspects by early afternoon.
