DOD Waiver and Release of Liability
Now that the DOD is an official IMBA chapter, we have certain legal obligations. One of these obligations is to make sure anyone attending a DOD sponsored ride or event signs a waiver and release of liability. We'll have forms to sign at all future events but you can also download the yearly form below, sign it, bring it to the next DOD ride and be covered for all rides for the rest of the year. Thanks for not whining too much about having to do this.
Directions to Whypass
Whypass is a network of singletrack trails built by the DOD near the town of Lorane, OR. The trails are not yet marked and it can be very confusing if you haven't ridden there before. It's recommended that you go with someone who knows the area for your first time out. Note: bringing beer for your guide(s) will (almost) fully guarantee your not getting lost in the maze.
Map of Whypass
Please be aware that this map of the Carpenter Bypass Trail System (aka Whypass) while reasonably accurate, is not a final and definitive representation of the trail network. It is a compilation of GPS tracks from 2010 since which time several trails have been wiped out by logging projects. We have made an effort to edit out all of the trails lost due to logging but there may still be one or two lines remaining on the map that have been decommissioned or rerouted.
Note: All trails falling outside of the blue quadrants are unofficial trails on private land and are not monitored by the BLM. Ride these trails at your own risk. In addition, trails on private land may be subject to seasonal or permanent closure at any time.
