Human waste is a big problem in Paria Canyon and Buckskin Gulch. These narrow canyons concentrate human waste in a very small area. A cleanup has been conducted yearly and large quantities of waste are packed out during patrols. At the same time a voluntary "Pack It Out" program was instituted. Your permit includes "Human Waste Bags" for each member of your party. You can pick them up at the Paria Contact Station, the BLM Kanab Field Office, or the BLM Arizona Strip District Office. They are easy to use, secure, airtight, and contain chemicals that neutralize odors. The majority of Paria hikers use these bags and have had no problems with them. They will be required for all Paria hikers beginning January 1, 2010. What about toilet paper? Burning or burying toilet paper is not permitted.
