Highlight: Magruder Corridor
The Magruder Corridor Trail is a very accessible trail for most vehicles that takes you into the scenic and remote wilderness. It is on many people’s bucket list due to the fact that this is the only place in the lower 48 where you can be in the middle of 5 million acres of wilderness. There is history at every corner with plenty of information along the way and available from the ranger districts at each end. You can see first hand how a forest regrows after a burn, there have been many big forest fires over the past few decades that have swept through the area, and you get the chance to drive directly through that area. Most of the areas have a healthy regrowth already and the burnt trees offer a beautiful contrast to the greenery and wildflowers when they are blooming.

Writer Information

Dennis Clark

Mapping Crew - California and Idaho

Dennis Clark was born in Los Angeles in 1942 and after 76 years of living in So Cal he moved to Emmett, Idaho with his wife Patricia, has four adult children with many grand and great grandchildren. He has loved the outdoors since his Cub Scout and Boy Scout days while camping with the family. He's an archer, hunter and fisherman but no longer wishes to harm animals. He has been involved with photography since the 1960's. He became more of a serious hiker in 2010 when he started Geocaching and has hiked the three tallest peaks in So Cal, Mt San Jacinto, Mt San Gorgonio and Mt Baldy, along with most of the lesser peaks in search of caches. Geocaching started his love for the USFS Trail system as he used the trails frequently to get to certain trailheads. He had a 2002 Ford Ranger 2wd and its amazing where that little pickup took him. In 5 years of weekly geocaching he was only stuck once in some Palm Springs sand. His 2016 Wrangler Sport Unlimited was purchased in 2015. He has become quite lazy in the hiking department as he can now drive to most locations. He's looking forward to posting some trails and don't hesitate to ask him for any help you might need.
