The Cinnamon Roll Crater in the Upper Crab watershed of Washington is a unique geological formation that attracts many visitors every year. The crater is approximately 3,400 feet in diameter and was formed from a volcanic eruption over 7,000 years ago. The name "Cinnamon Roll Crater" comes from the distinctive swirl pattern on the crater walls, which resembles the popular pastry.

One of the main reasons to visit the Cinnamon Roll Crater is to hike to the top of the crater and take in the breathtaking views of the surrounding landscape. The trail to the top is a moderate hike, with several switchbacks and a gradual climb up to the rim of the crater. Once at the top, visitors can look down into the crater and see the unique swirl pattern on the walls. In addition to the scenic views, the Cinnamon Roll Crater is also an important scientific site, as it provides geologists with valuable information about the geology and volcanic history of the region.
