SIERRARIOS MEMBERSHIP: By joining SierraRios as a member you will help support river conservation goals in Mexico and Latin America. Initially this is through documentating and providing information regarding rivers in the region. With each $35 contribution you will receive:

1) GUIDEBOOK: one copy of a book covering part of Latin America - currently "Mexican Whitewater: Norte". Membership dues include shipping and tax within the USA or Mexico ($10 extra shipping charges will apply elsewhere; click here). In the future, three additional guidebooks will be available to Mexico: Occidental, Oriental, Sur. A fifth will cover the Maya area. [NOTE: as of June 7, 2011 there are no more books available. You will have to wait until another printing to receive the book.]

2) DVD: showing descents of various rivers in the area covered by the guidebook ordered. Currently, this is 1 hr of edited videos to the Copper Canyon region (see DVD image).

3) TOPO MAP ACCESS: you will receive a password to access annotated topographic maps of the rivers in the region covered by the guidebook received. These maps are ideal to print out and bring along on the trips and also may be for first descents. [example map (Tomochi)]
