is a community driven online index of technical climbing routes worldwide. The focus is on technical rock, ice, mixed and bouldering routes, but some alpine climbing routes have been added to the database. Although there are sections in the database for international routes, the bulk of the routes posted on the website is centered around the western United States. Because the database is contributed by the users, this resource tends to be the most up to date guidebook for the active areas.
Users are allowed to contribute areas, sub-areas and routes to the database, as well as images, rating adjustments, quality stars and comments. Each user has a user page where they can track tick lists, todo lists and their contributions to the site. There is a ranking system similar to SummitPost, but without the weighting system for users with many contributions. The site also hosts forums and a Partner Finder database.
