The Porter Fork drainage is located in Mill Creek Canyon. It is a big, north-facing drainage with numerous subdrainages. Gobblers Knob and Mount Raymond are at the upper end of Porter Fork and form the upper ridgeline between Mill Creek Canyon and Big Cottonwood Canyon.
Porter Fork has steep avalanche paths and has been the site of numerous avalanche accidents and fatalities.
The Porter Fork road is a safe, low-angle tour on an unplowed cabin road. Park at the Porter Fork trailhead and skin up the road to the last cabin. Skiing beyond the last house exposes you to the West Porter Fork avalanche path.
About the name
Porter Fork was named after Chauncey Porter who built a lumber mill near the mouth of the drainage in the 1950s (the third mill in Mill Creek Canyon). His mill was destroyed by fire.
