Investigators are trying to figure out who was growing hundreds of marijuana plants in Pike National Forest.
The plants were found in the Buffalo Creek area that burned during a wildfire that destroyed seven homes in 1996.
Authorities say two out-of-state hikers stumbled on the 294 plants while looking for scenery to photograph.
Jefferson County sheriff's office spokesman Jim Shires says the operation was fairly sophisticated, with a ground cover to keep moisture in the soil during the current hot spell.
The plants were four- to six feet tall and have an estimated street value of 150-thousand dollars.
