Arches National Park has over 2000 arches— the greatest concentration of natural arches in the world. There are arches and fins. Fins are giant walls of rock that were once part of one flat layer of sandstone. Forces deep underground cause the rock to bulge upward and crack in a series of roughly parallel lines. Rainwater seeped into the cracks, dissolving the minerals that bond the stone together. Fins may become arches. Arches eventually collapse.

We started the day with a hike to Broken Arch. There were only two other people on the trail, and the sunrise light on the rocks was beautiful.

After breakfast, we hiked up to several arches. There were lots of people on the trail; heard languages from all over the world.

The campground is a black sky location which means artificial light is at a minimum and the sky is a dazzling array of stars.

We definitely want to come back here again.
