You can trigger an avalanche on some northerly and most easterly-facing slopes, especially at upper elevations. The most dangerous areas hold drifted snow on steep slopes just below ridgelines, convex rollovers, and cross-loaded gullies. Look for and avoid steep slopes with textured snow or pillow-like drifts. Drifted slabs might extend farther down the slope than anticipated.
Avalanches might break within the most recent snow from March, but the bigger concern is slides stepping down into more deeply buried weak layers from February. You might not see any signs of instability like cracking or collapsing before you trigger a deeper avalanche. Look for safer riding on wind-sheltered slopes or slopes less than 30 degrees.
Accumulating snow won't raise the danger on Thursday, but look for snow to begin around midday along the Continental Divide. The danger will likely increase on Friday.
