Our tent at Grizzly Lake. In order to preserve the landscape in Tombstone Territorial Park and also to help prevent grizzly bear encounters, all backpackers are required to camp at several designated campsites along the range. Each tent site has an elevated tent pad, and there are ropes strung along the paths to keep people from trampling the fragile and squishy tundra. There are also outhouses, cooking tents, and storage lockers to keep food away from the bears. I think much of this didn't exist until recent years, but it's probably a good thing as the range inevitably becomes more well known.
