New field trip posted: Geology guide to the Hidden Lakes Trail, North Cascades

The best of the dike exposures is just west of the saddle between the two Hidden Lakes Peaks

This summer I hiked the gorgeous Hidden Lakes Trail to the eponymous restored fire lookout. A wonderful, all day geology hike, to one of the most breathtaking views into the glaciated peaks of North Cascades National Park. I just completed and published the Hidden Lakes geo guide.

Here you can see ancient Napeequa schist, the granodiorite that intrudes it, several volcanic ash layers, dark dikes cutting the granodiorite, and some wall-rock xenoliths in the granodiorite just below the lookout. Get going my friends, snow is coming.

Take me to the new page right now!
