With Lomatium farinosum and Allium scilloides on particularly rocky patch.
Scale in photo 2 is mm (smallest division). Draba verna at top right of first photo.
This plant is usually identified from much larger specimens on richer soil but I think this is the form seen on poor rocky soils like this. There are a few photos of this tiny form at https://burkeherbarium.org/imagecollection
In some areas nearly the only plant currently green where fire was a year ago.
