Introduction[edit]
This is an absolutely spectacular backpacking canyoneering experience, quite possibly the best on the Colorado Plateau, maybe even exceeding West Canyon depending on your personal tastes. Up Long Canyon is not technical, but there are two or three challenging up-climbs that will be nice to have assistance. The crossover between Long and Gravel is a legitimate challenge when it's warm. Be prepared to start as the sun is coming up and pack a lot of water; six liters is a good choice. It can take a while of going down Gravel before you find water. We found it where the first camp in Gravel Canyon is shown on the map (Camp 3 waypoint). Gravel Canyon has a few rappels to 70 feet. Bring a very trusty water filter. A pre-filter (coffee filters or an MSR SiltStopper if you can get ahold of one) is highly advised. We killed three of the squeeze style filters going up Long alone, even with back flushing and visibly clear water to filter. We had a friend bring in a Katadyn Hiker Pro with an MSR SiltStopper when she joined on day four that saved the rest of the trip. Steve Allen's Canyoneering 2: Technical Loop Hikes in Southern Utah documents this loop pretty well. I've done this loop two times. Once in six days with more weight, not knowing the loop very well, and didn't get to do side canyons. The second time was with a very light and fast crew over seven days. We did seven side canyons that were all very good. The most important parts on the attached kml map to pay closer attention to are the exit from Long Canyon and the drop off of the rim shortly after leaving the road during the transfer day. Before leaving Long Canyon, it is worth exploring the short hike from the exit to a dryfall / cliff that impedes further travel up Long. The exit out of Long Canyon on this track is shorter and easier than the one documented in the book; I've done both. The labelled climb up on the transfer day isn't super hard, but it's worth getting out the rope to pull up the packs. If you plan to do the trip alone, make sure that you are a strong climber to be able to do this climb with a pack on. After the climb, be sure to turn right (South) and go look out at the end of the knoll before continuing on. The view here is impressive out over Long Canyon, Jacob's Chair, and the Henry Mountains. Jacob's Chair will be a good landmark to give you perspective of where you are throughout the trip. Not long after the climb, you will hit a jeep track road. After leaving the road, there is only one break in the cliff band. It must have taken some time to first discover the break as it is well out of view for a ways. Once down off of the cliff band, you walk across the desert for a couple miles to a side canyon that flows into Gravel. Don't drop into the side canyon, walk along the rim on the right (South) side. When you reach the rim of Gravel atop the end of the side canyon, the track of the drop into Gravel is not accurate as I just drew that part in. You'll see the route clearly, as there is an obvious trail. While going down Gravel, there are three times that it matters which rim you choose. I labelled them on the map. The labelled campsites are very good choices. If you plan to do Cowboy Canyon as well, make sure to follow the Cowboy Canyon track when climbing out of Gravel correctly. If you rappel in Gravel just below the listed camp near Cowboy, you will not be able to get back up. The rappel just below where Cowboy Canyon comes in is one of the most unique and beautiful rappels on the Colorado Plateau. The full loop alone is 32 miles. Add more for whatever number of side canyons you choose to do. The side canyons are absolutely worth allotting time for! Both times that I've done it were in early May, which seems like an ideal time to be there.
Approach[edit]
The approach is to start going down White Canyon until you reach Long Canyon.
Descent[edit]
Going up Long and down Gravel could be considered the "Descent." The side canyon mentioned in Steve Allen's book is labelled 6281T on the kml map here. I've done this canyon with the shown approach, but it looks like there is another approach right up along side of the canyon after getting up the first climb up out of Gravel that I would do if I did it again. This side canyon is definitely worth adding, especially if you are just doing the standard Gravel Canyon route. A sandtrap is a great addition for the 6281T side canyon. I would suggest a 100ft rope for that one if you're adding it to the standard Gravel descent. We all took 3mm farmer johns and were good when highs were around 70 to 75. We only needed them in Gravel even with Long being totally full from a recent rain.

Background[edit]
Gear list that was used:
70+ liter backpack - know that it will get beat up some. Hyperlite Northrim is a very good choice.
Sleeping bag (A Sea To Summit Spark 28 worked great), sleeping pad (Thermarest NeoAir), optional pillow, ground cloth / tarp (Tyvek, tried Polycro, but it's not tough enough for this trip), breathable emergency bivvy (i.e. SOL Escape Lite)
Dry bag(s): The Sea To Summit 65L is a good starting point with secondary thin, smaller dry bags to go over the most important things like clothes, food, and sleeping bag.
Lightweight harness (lightest is the Camp Alp Racing Harness), 2 screwgate carabiners (Grivel K3N is the lightest), rappel device (DMM Mantis is only 45 grams), climbing helmet, volleyball elbow pads (Bodyprox makes good ones)
Wetsuit (full 3/2 or farmer john depending on water levels) and thick wool socks. The Neosport Waterman John 3mm is extremely light and cheap. We used the Waterman and were comfortable.
Water purifier – Katadyn Hiker Pro with an MSR Siltstopper. Some PolyAluminum Chloride (PAC) flocculant in case of silty water.
Stove (BRS-3000T), fuel canister(s), pot (MSR Titan), lighter, spoon/spork. One stove / pot for every two people to save weight. A single 4oz fuel canister will last one person seven days.
Water reservoir - 3L Platypus Hoser and 3 liters of water bottles. Start the connect day with 5+ liters.
(Optional) First aid, blister pads, sunscreen, anti-inflammatory drugs, whistle, headlamp
Tough approach / hiking shoes and light gaiters (Dirty Girl Gaiters are nice). Optional: Crocs / sandals around camp - I did not bring them.
Clothes: Lightweight rain jacket (Frogg Togg Xtreme Lite is ultralight & cheap), long sleeve shirt, short sleeve shirt, light puffy, thin pants/tights, thick wool socks, polyester board shorts, canyon gloves, full coverage hat, maybe a bandana.
Food: I took 18lbs of food, which was 4,200 calories per day over 6.5 days. I only ate 16.5lbs of that. When I do it again, I'll aim for 3,800 calories per day. I weigh 190 to 195lbs.
Group gear: 75’ Slyther rope, 80’ Imlay pull-cord, fiddle stick, and roughly 60’ of 5/8” webbing.
My pack was 40lbs at the start of the most recent trip. I'm pretty sure I can get it down to 38lbs for a future trip.
