Part of the job of preparing beds in our newly constructed high tunnel hoop house is removing more than a few large rocks of varying size lurking just beneath the surface of the soil.. I pulled this one out last night. It is, by no means, not the largest rock I have extracted.
A glacier really did a number on our Skykomish river valley during the last ice age. Our top soil, ranging in depth from 1′ to 2′ in thickness, sits on top of a concrete-like layer of sand and gravel compressed by the huge pressure of the passing glacier. Sitting on top of this compressed layer are rocks ranging in size from soft ball size to automobile size.
