These may look like trees killed off by a wildfire, but in fact are what are known as "Bobbysock trees" or "silent dog trees". They are trees that have grown where a newly formed hydrothermic area has moved into. The trees take up an abundance of dissolved silica which interfers with the sap movement which kills the tree, leaving behind the white tissue exposed as the bark falls away...hence the silent dog tree...no bark.
