Staying at Signal Mountain Lodge, we felt like we really should visit the top of Signal Mountain. Since we were traveling with an octogenarian, we decided it would be better to drive up the mountain rather than hike. We visited on a cloudy evening, but the view was still lovely. At least until the snow squall hit. We took a quick selfie and headed back to the car.
On my walk back I noticed this little metallic marker in the blacktop. After a little research I discovered it's a geological survey marker and there are over 200 of them in Grand Teton National Park. These metal disks are used to mark key points on the Earth's surface, and maintain a coordinate system to keep track of latitude, longitude, and elevation of specific places. After noticing this one, I tried to keep my eyes open for them as we traveled through the park.
