From Avalanche Peak you can descend into the Crow valley on the west. However, the route makes a big detour to the north, because that's where you'll find a steep scree slope all the way down to the valley.
If you don't go north far enough and take an earlier scree slope, you'll stand an excellent chance of falling to your death if you're running the scree and can't stop fast enough when it gets too steep, or, if you see the danger before it's too late, you'll have to struggle all the way back up the scree.
There are several ways to recognize the top of the right scree slope: there is a big cairn on the ridge; the ridge becomes markedly steeper further north after that; you can see the scree leading all the way down to the valley floor.
If you don't know the route, don't try it in poor visibility.
