PINEDALE — Porcupine Trail on the Pinedale Ranger District, located on the Bridger-Teton National Forest (BTNF), is obstructed by an avalanche of snow and debris. The affected area is three miles south of the Shirley Lake Trail junction (T38N R108W S31).

The avalanche consists of a mixture of debris and heavily compacted snow, with Porcupine Creek running underneath. Porcupine Trail is impassable for three fourths of a mile going south. Travel by foot or stock is not advised due to hazardous conditions. There is signage warning visitors of conditions at the Green River Lakes and New Fork Trailheads.  Recommended alternate routes for those interested in recreating in the area include Highline Trail, New Fork Trail or Clark Creek Trail.

The Pinedale Ranger District advises wilderness visitors to be particularly cautious this season due to lingering snow pack and very high water levels making river crossings very dangerous.  Prior to back country travel always notify someone of your itinerary and expected time of return.

Further information regarding the Porcupine Trail and back country conditions is available at the Pinedale Ranger District, 29 E. Fremont Lake Road (307-367-4326) and online at www.fs.usda.gov/btnf under “Alerts & Notices.”
