Here's what Blackbird Mt Shasta guide Mike Henry said about conditions for climbing and skiing on Monday, May 1, 2024:

Here's what I'm seeing on the mountain today. I did a tour up giddy giddy gulch up to the point where you can drop into either the lower portion of Casaval Ridge or on the other side into Avalanche Gulch. I chose Avy Gulch to get a look at that side as well.
It's really clear the wind did a number on the snow. With elevation gain, skiing becomes progressively more firm with a widespread breakable crust. Ridges and high points in the terrain are completely scoured to the old snow surface as well. Wasn't the most pleasant skiing today. I thought it would be better, honestly.

Today, there was little to no warming above 7800 ft. so there really hasn't been a shed cycle yet. I’m concerned Wednesday & Thursday might be the days when things start to slide due to rapid warming like the forecast is calling for.

Overall, I think in order to get good skiing on Shasta right now, we need a few melt freeze cycles. 1, to smooth the snow surface & 2, let warming shed the new snow.

With reactive wind slabs causing multiple serious injuries on the mountain in the last two weeks, climbers and ski mountaineers should exert extra caution with the new snow and make careful evaluations of the snowpack before exposing themselves to avalanche hazard.  Unsettled weather in early spring can make for hazardous conditions on Mt Shasta and if you don't have confidence in your decision making with severe weather and snowpack evaluation, you should hire a guide on Mt Shasta or turn around before exposing you team to avalanche hazard. 

Remember, avalanche hazard can be difficult to predict from below and often teams move into the reactive slab before they're able to detect the dangerous slab that is lingering above them.  Wind slabs should be considered guilty before proven innocent - don't climb into a slope that could contain a large wind slab overhead!
