Full Briefing
The Red Flag Warning (issued NWS Pueblo, expires 8 PM MDT today) is your first-day logistical constraint. The warning reflects low humidity and sustained WSW winds of 15-25 mph — not a fire threat given no active fires within 50 miles, but it does mean cold, gusty conditions on exposed ridgeline terrain this afternoon. Get moving early, use the mostly sunny window, and be in a sheltered camp well before dark. After tonight, the pattern flips firmly to winter: 68% precip chance tonight, 93% Sunday, with snow showers likely through Monday. Highs stay at or below freezing (31°F Sunday, 31°F Monday) with overnight lows dropping to 16-19°F. This is a legitimate late-April snowstorm — budget for accumulation on top of the existing 37-inch snowpack and expect slow, postholing travel on unbroken trail sections.
Avalanche danger is Low across all elevations with no identified problems — clean bulletin from CAIC. The 37 inches of snowpack on the ground is well-settled at this point in the season. You're not carrying avalanche risk on this trip; the snow is just an obstacle, not a hazard.
Stream crossings are a non-issue right now. The USGS gauges showing in the data are California stations that appear mismatched to this location — disregard those specific numbers. What matters here: with highs at or below freezing through Sunday and Monday, snowmelt is suppressed. Expect crossings to be at or near their lowest daily flow in the mornings. If temps recover later in the week, afternoon flows will rise, but for your three-day window, crossing difficulty should be minimal.
Note that the SNOTEL elevation figures in the raw data (6,021 ft for Annie Springs, 840 ft and 1,348 ft for the others) don't match the Collegiate Peaks terrain — treat those as data artifacts. The 37-inch reported depth is plausible for this area in late April and consistent with what you'd expect on a route that crosses above treeline. Travel-wise: your best window is this afternoon before the snow starts. Sunday will be slow and potentially whiteout on exposed sections. Plan to hunker or move conservatively Sunday. You've got 13h 37m of daylight working for you, so even a late start Monday still gives you a full travel day to finish out the loop.

About This Route
The Collegiate Peaks Wilderness in central Colorado offers a challenging loop route through some of the state's highest peaks—all named after Ivy League universities. The route circles through alpine terrain between the towns of Buena Vista and Leadville, crossing the Continental Divide multiple times. The loop connects segments of the Colorado Trail and Continental Divide Trail, passing beneath Mt. Harvard (14,420 ft), Mt. Columbia (14,073 ft), and Mt. Yale (14,196 ft). The terrain alternates between dense spruce forests, alpine tundra, and sweeping above-treeline ridges. Water sources are generally reliable from snowmelt streams, though some sections can be dry in late season. The loop crosses several high passes above 12,000 feet where weather can be severe. Start early each day to avoid afternoon thunderstorms, which are almost daily occurrences in July and August.
