Northern California Bouldering includes more than 700 boulder problems ranging from the Bay Area to Tahoe, and extending north along the coast. Classic areas such as Donner and Castle Rock are included of course, but there are also 10 completely new areas and more than 200 problems that have never been covered in a guide before. Author Chris Summit personally climbed nearly all of the problems in the book in order to get the most first-hand, insider beta possible.
