Collegiate Peaks Loop

NWS Pueblo has a Winter Weather Advisory active through 5 AM Thursday. Today and tonight you'll see snow showers with 86–90% precip probability and overnight temps dropping to 13°F at elevation. This isn't a sketchy early-season dusting — plan for meaningful accumulation on the trail and significant wind chill. If you're starting today, your first night is the hardest: cold, potentially wet, and you'll be setting up camp in conditions that punish slow systems. The storm clears Thursday morning and you get two solid days with sun, light winds 5–10 mph, and highs around 28–29°F. Friday night drops to 11°F, so keep your water bottles inside your sleeping bag.

Avalanche danger is Low (1/5) across all elevations with no problems identified — that's a clean bulletin and a non-issue for this trip. The Collegiate Peaks Loop doesn't have heavy avalanche terrain in the traditional sense, and at Low danger you have nothing to manage there.

The stream crossing data in this briefing is incorrect — the five USGS gauges shown are in central California and have zero relevance to the Collegiate Peaks area. Do not use those flow numbers. In early November, Arkansas River headwaters are typically at low-to-moderate seasonal flow, but snowmelt is largely done and temperatures will stay well below freezing overnight, keeping flows stable and low. Crossings on this route are most likely straightforward, but you won't know if any snow slush or ice is making banks slippery until you're there. Expect icy edges.

Daylight is your real constraint: 10h 26m with sunset at 5:03 PM. At elevation in November, usable light starts going flat by 4:00 PM. Plan for 8-hour hiking windows and have camp selected and set up by 3:30 PM each day to avoid cold, dark setup. Thursday's sun window is your best mileage day — push hard then. No fires within 50 miles, no smoke concern.
