quartz block
A block of nearly pure quartz near the shore of Star Lake, Mt Madison NH.

Blocks like this (but mostly smaller) occur occassionally throughout the northern Presidential Range - you see them on the summit cone of Mt Washington in particular, where they're easily mistaken for snowfields. Breadloaf-sized quartz pieces are frequently used as the top stone in cairns for marking trails in the Presis.

I think I can see this block in satellite images.

that is a lot of quartz all together! Very neat! It is the most abundant mineral on earth though...
