Trinity Alps Traverse

The weather window is legitimately good. Highs in the mid-40s to low 50s through Friday with clear to mostly sunny skies and light NW winds the whole trip. Overnight lows will hit 29°F tonight and hover in the low-to-mid 30s each night after that — cold enough that you want a solid three-season or light four-season setup and a good sleep system, but nothing extreme. No precip in the forecast at all, which means stable trail conditions and no new mud or water additions from rain.

The USGS stream flow data in this briefing is not from Trinity Alps drainages — the gauges referenced are pulling from the Salinas River watershed, Llagas Creek near Gilroy, and Alameda Creek near Sunol, all 150-200+ miles away. That data tells you nothing useful about Stuart Fork, the South Fork Trinity, or any other crossing on your route. Early November in the Trinity Alps typically means post-first-storm flows that can be surprisingly robust, especially if there's been any early-season precipitation in the past two to three weeks. Without reliable gauge data, scout every ford. Use poles for balance, unclip your hipbelt and sternum strap, and move crossings to early morning when overnight temps have suppressed any residual snowmelt contribution — though with zero snowpack at all monitored stations, snowmelt isn't a factor right now.

No snow on the ground at any SNOTEL station, including Annie Springs at 6,021 feet, which covers the higher terrain you'll be moving through. That's a clean green light for trail navigation and pass crossings — no post-holing, no ice on the approach. The lack of snow at elevation in early November is unusual but straightforward: you're moving through the Alps in late-fall dry conditions.

Daylight is your real logistics constraint. You've got 10h 19m of usable light with sunset at 5:05 PM. Plan your camp arrivals before 4:30 to have time to set up before dark. If you're doing any significant elevation gain on day legs, start moving by 7:30 AM. Golden hour starts at 4:25 — if you're not camped by then, you're setting up in the dark.
