Interesting time yesterday. This was a non technical ride that any level of Jeep should be able to do; coming out of the Preserve in the Piute Range has a rough road that will require a bit of straddling by the short Jeeps (I have a stock 03 Rubicon and did not scrape once and my better half did not have to get to spot once for reference).
What does this trail officer? SOLITUDE and Piute Canyon (pic below) were the highlights. Snow throughout was a bonus, but we all know that is temporary.
Time: Left Henderson @ Eastern: 1130 and arrived at 95 @ 1540
Gas: Full leaving Henderson, just above 1/2 tank when we hit asphalt / 95
Total mileage in one big loop: 180 miles
Ivanpah Road can be done by 2 wheel drive vehicles (perhaps not yesterday with the snow...) and speeds average 10 to 40 mph (light rough sections and some washboard).
Trip Notes: On the Preserve Map, Fort Piute and the Piute Canyon Trail look to be notable destinations ie. the road should be notable/well marked. In reality, I believe that while the NPS might have had development plans once upon a time, those have went to the wayside over time. The trail out required some route finding (the intersection/lead out to the east from Ivanpah Rd was not marked--I have Gaia GPS App on my phone with the NPS overlay map and my spouse navigated / confirmed our track after we SWAG'd it). The trail east is 4x4 only--I probably averaged 15-20 mph (it was smooth for the most part and the snow helped) with being right at 9-10 miles to the canyon (straight line east on map).
There were two good tracks (3 total trails--but I kept to the close dashes when able) going east (yellow line is over the one we chose). I am glad that we did as we would have missed Piute Canyon which was a welcomed surprise.
Coming over the Piute Range, that road was rough. It has had some significant engineering in the past (culverts, etc), but I'd guess 15-20 years since a bulldozer or grader has been through there. It IS non technical, but not fast. Once down to the bottom, you have 8 or so miles of sandy road to US 95.
That stated, we had planned on coming through the Range and going up to the Old Fort Piute/Piute Springs, but since is was past 1500, we kept on going to 95. We decided to keep Fort Piute for another time and we when do, we will come in from US 95. Note that we took the southern trail from Piute Range to 95. Old Mohave Road is a mile or so north of it. Once we hit 95, we cased out Old Mohave Road from the asphalt. The southern road looks to be the faster, so pick your poison accordingly.
