Best Dispersed Camping near Caribou-Targhee National Forest

Stayed at the trailhead parking lot boondocking (No toilets, no water, no electric).  Fairly level area with a fire ring, picnic tables under a shelter, metal charcoal grill and easy access to the lava field (Hells Half Acre) hiking trails.    Access from US 20 to the trailhead parking is gravel and easily accessible for all vehicles with several large turnouts that can be camped at.  The rest of the loop past the turn to the trailhead parking is not graveled but still passable by most vehicles.  I would be more hesitant to use the loop in wet weather where the ground may be soft.

Unfortunately as you can see in a couple of the pictures not everyone cares for our public lands appropriately, there is some garbage left around and someone has taken it upon themselves to use signs and structures for target practice.

Blackrock Canyon BLM Pocatello, ID 8/4/22 DO NOT trust APP coordinates 42.8145, -112.3307 : Campendium 6/20/22 42.8146,-112.3307 : The Dyrt 6/30/22, 42.8142, -112.3306 : FREE Roam / 2019 These coordinates all lead to a reasonably level, fenced dirt parking lot on the left with a vault toilet and concrete walkway going across the road to a covered picnic/stream area. We were very excited. This is NOT the BLM camping area.... or rather more likely, 'no longer' is? There are 3 new looking signs stating Day Use Only, No Overnight Camping. However there is still a signboard by the toilet with the typical BLM rules/regs & 14 day limit? What's a gal to do? So I called the BLM office listed on the sign to clear up the conflicting sign info. Yep, the aforementioned parking lot is NOT FOR OVERNIGHTCAMPING - again, signs are shiney, no weathering, so this may be a new development? We were told there are 2 BLM camping areas. #1 is ACROSS from the aforementioned parking lot... big DEEPLY graveled area on the right as you come in that steeply slopes down to the picnic table area (our autolevel just laughed at us no matter what we did or where we positioned). #2 is about 1/4m further up where the road loops back on itself, and also has a vault toilet (no concrete walkway). This is a medium parking area inside the loop. Looked doable until we noticed the berm hiding under the grass. At 34' backed in, we'd have either lost the under carriage spare tire, or had our big butt sitting on the ground. So this too was a big nope for us. There is a pullout on the way to the 2nd area, but currently has a 'road closed' sign on it, and another pull out just before the 1st parking area. We could have squeezed into this one, but by this point we were wore out & the thought of all the dust ... just nope. We moved on. This is a GORGEOUS area, if you're a smaller footprint, and can get level. Verizon & ATT both usable but not very strong. Road in is a little washboard and hilly, but doable. I15 underpass ... we're 13'8" on truck & cleared both with no issues. Definitely recommend dropping your rig in the parking lot and scouting out this area 1st.
