In the early morning Sunday, snow was frozen hard at all elevations. Bright sunshine softened slopes below 7500' by mid afternoon, but a 25 mph wind may have slowed snow warming above 7500. There were no signs that any avalanche activity occurred on Saturday 4/23. Descending from the rim between 2 and 4:30 PM on 4/24, I saw no avalanche activity above 5500', but there were a number of loose wet avalanches between 4500 and 5500'. The snow was wet and soft and boots on untraveled snow sank 8-12". I also saw an impressive roller ball greater than 3 feet in diameter.
I number of skiers and climbers that I spoke to had seen the avalanche activity and were avoiding potential terrain traps.
