The Boston Mountain Range consists of high-quality sandstone and is host to such popular areas as Cave Creek and Sam's Throne. Many of the cliff lines are hard to see from any roads, as they are set down in wooded valleys.
PLEASE NOTE!!! It is NOT considered proper to hang permanent draws or chains in this area, especially on already established climbs. It is also STRONGLY discouraged on new lines that go up.
The northwestern part of the state. Cities to look for include Harrison and Mt. Judea.
Cole's book is a nice color guide with nice action photos. The book down grades many routes. I have been climbing in Arkansas for the last 20 years and am taken back by the the multiple down grades on routes that have been established and confirmed by many climbers over the years. Ratings should not be down graded once you have dialed the route and decided that it is easier. Grades are set for on-sights not rehearsed work sessions. Clay's book gives a more realistic rating of the routes in my opinion.
The National Forest Service is currently conducting a Heritage Site Review at Hudson Mountain and the Invasion Wall climbing areas near Cowell, AR during the month of August. The FS is asking that climbers, hikers, and all other users avoid these areas during the review process. Please respect the USFS request and pass the word on to other climbers.
