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

The best of the dikes is just west of the saddle between the two Hidden Lakes Peaks. Click to enlarge.

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!

Mobile users: Displaying this website on your smart phone

I don’t have a smart phone. So I didn’t know this until the other day. If you use a mobile device, this website may not display well. You can fix that- I just figured out how. Bring up this page on your device, and scroll aaaaaaall the way to the bottom. There will be an option to ‘display full website’ or something to that effect. Tap that, and voila, the website will look like it is designed to on a desktop, with all the tabs. Much easier to find your way around. OK, so maybe I’m just a troglodyte [thanks to Spiro T. Agnew for popularizing that wonderful word back in the 1970s] and everyone knows how to do this. But I suspect some folks don’t because they have mentioned this problem to me. Give it a try. What I don’t know is whether this will always open this website to the full screen view, or whether you have to do that every time. Someone please let me know via comment.

Your semi-luddite friend.
