Blanchard Mountain/Oyster Dome geology

Dave Tucker's Northwest Geology Field Trips blog has some great posts on the geology of the Chuckanuts and Blanchard Mountain. Did you know that Blanchard Mountain and Mount Shuksan are made of nearly the same rocks? How did all that giant talus form below Oyster Dome? What causes the honeycombing effect in Chuckanut sandstone along the shore? What's with all the fossils?

Be sure to check out the long list of topics Dave has compiled over the past few months--very impressive stuff and a lot of fun for experts and non-experts alike.
