Highlight: Dusy-Ershim  Trail
If you haven't heard of the Dusy-Ershim trail yet, you will soon. Many believe this is the newest hardest multiday off-road trip you can do today. The trail is comprised of both overland and rock crawling. If you ask someone that has recently done the Rubicon, they will say this trail is about 3-6 times harder. The Dusy-Ershim offers some of the hardest wheeling around, from mile long rocky hill climbs, to very technical obstacles, to some of the most amazing camping & fishing you have ever done in your life. The views have something to be said about too. Just be warned, this isn't an easy trip, even the most built rigs will leave this trail with mechanical failure. Be prepared, because body damage is almost guaranteed, even for the best drivers. If you are up to the challenge, expect the trip to take you in the range of 3-5 days.

Mapping Crew - California

Joshua Noesser grew up in Southern California but has lived in different parts of the country during his young adult life. Josh was first turned to four wheeling when he road with one of his friends dad up Surprise Canyon in the Panamint Valley at age14. After nearly 3 different roll overs later and a half dozen intense waterfalls, Josh was hooked. At 16 he purchased his first Jeep a CJ 7 and by 17 was putting his first locker in it. Currently, Josh is the owner and CEO of Nybble, an IT Solutions Company based in Orange County, California. Nybble isn't your normal IT company where everyone stays in and plays video games. Nybble's average company trip is out on the trails since a good amount of his staff enjoy wheeling too. As Josh likes to say, he offers the only IT Company with the ability to provide services in extreme locations. "If you want a server at the top of The Hammers, we will take care of that for you." Today you can find Josh out on the trail behind the wheel in one of his three different off-road vehicles. See the vehicles below for more information. If you ever run into Josh, please say high, he is a very friendly person and is always happy to have a new person join the group.
