80' rope is plenty after car bumper rappel.

Dry. Just a few muddy spots despite rain a few days earlier. No rain for a while before then.

Roads are beautifully smooth. Graded May 16.

Busy: 4 cars at TH at 7:30 AM. 6 cars at TH at 11 AM.

Good curvy canyon. Not too challenging, just awkward contorting and scraping. A little stemming.

No daddy longleg nests yet, but some on walls. Mosquitoes.

2 skinny ppl, 3.5 hrs with short breaks to pack gear and patch a blister.

Several camping spots near trailhead. Local etiquette: pack out poop.

Took our group of 7 (with ~2 beginners) about 6 hours, though I'm sure this was largely due to the fact that the canyon was very dry. We also only ever rappelled twice (off the bumper and over the pot hole). The rest of the rappels were easier as downclimbs/handlines. The pothole only had some water off to the side, so you could stand in it without getting wet. There were pockets of water throughout the day, and most group members got wet up to their ankles, while others stayed dry. Beautiful weather this time of year. Great day overall.

Totally dry right now. Contrary to some beta, you can do the first rap with a rope about 125’ in length.

Totally dry. Rappelled the pothole drop, downclimbed the rest. No spiders. Webbing at the pothole drop was in good condition.

4/28/18 - The first big pothole above rap2 is completely dry but there are plenty of knee/waist deep pools throughtout the rest of the canyon. After the final dark section and before the canyon opens up we saw 3 rattlesnakes. My 130ft rope reached the bottom of the first rappel perfectly. Beautiful canyon and a lovely hike back to the car

Anchors in good shape. The pothole webbing always looks a little worn. The one bolt near the end has been removed? Why? It was neither necessary nor unnecessary, and was certainly well-placed to be hidden.

The canyon was somewhat wet from the rains the night before. Knee to mid-thigh deep, depending on height. It was cold, but nothing worth bringing a wetsuit for. Maybe neoprene socks, but we only had wool socks.

The road out to there is in pretty good condition, but with a lot of built up sand. Drive-able by some low clearance cars. Our Nissan Altima made it all the way. But the main road getting to the Roost area itself has some bad washboard sections right now.

Very busy weekend, had to wait our turn to set up the entry rappel. Emery County Search & Rescue was training at the trailhead (and waiting to be needed). This canyon gets down to business immediately dropping very deep very quickly. If you're not comfortable with lots of sketchy chimneying find a different canyon. Three big pools. 2 of them avoidable with full body stems and/or being 30-40 feet off the deck. Couldn't figure out a way around the other pool, about knee deep. Anchor from the pothole looked solid. Make sure you use safe techniques on some of the larger drops down in the depths. One of our party jumped down a 7 ft drop and rolled his ankle pretty bad on an unseen rock just under the sand. Awesome canyon, lots of fun. Great hike out. 3 people (one with a bum ankle) 5 hours car to car

Water up to knee deep in several spots. Pothole dry, anchor in good condition.

First rappel is not as long as beta indicates, but perhaps depends on how close to the edge you park your vehicle. Canyon still has water in a couple spots to upper thigh level and several other muddy spots, so wetsuits not necessary. Some pools are cowpie soup. Can see how muddy boots can be challenging in certain spots. Must be very careful not to slip. This canyon starts off moderately challenging for the first half, then it gets seriously down to business for the second half. Headlamps useful in 2 -3 areas even on a nice cloudless day. Last drop has a webbing handline down into a knee deep pool. Long hike out at end of day. Would consider this overall to be a little more physically demanding and technically challenging than Middle Fork Leprechaun for comparisons sake. 6.5 hours car to car for group of 5.

From talking with people I was expecting 2-3 'tight' spots with the one 30' 'up and over' in the final 500' of squeezy canyon being both the tightest and the grand finale. Uhhhh . . . there were MANY tight spots and tight corridors that I climbed up and over, usually using chimney technique of back on one wall knees or feet on the other.

There were many corkscrewy sections, a few potholes that could be avoided I would not have wanted to drop into and have to escape. We had mud and water to the waist a time or two but all and all it was drier and cleaner than I expected; though with many more places the walls pinched both my back and sternum.

Taking a small pack, as suggested, was very helpful in dangling it off a bunny strap/ harness on many, many occasions.

The walk out took surprisingly longer than I had expected. A 5 minute detour out to the point of land near where you reach the rim rock is well worth the view.

Beautiful canyon, very skinny. Lots of rank potholes, mud, etc. No swimming, though.

Temps were perfect for the exit hike and it is beautiful. I enjoyed the hike out almost as much as the canyon itself.

There was an RV at the trailhead so you could probably get a passenger vehicle down there.

First time descending Alcatraz and it was sweet! Water up to knees in some places, and the pothole was dry. Road was in very good condition. High clearance vehicle was not required.

our second time doing Alcatraz, and it was just a challenging as the first time (2009). Waist deep water and there was water in the big pot you have to rap out of. 5 out of 5.

Water level waist deep. No water in rappel pothole, anchor good. Just a few groups in the canyon( 5 cars with rap ropes parked at the drop off)

Thigh deep water in a few spots, not bad. We pulled all of the bolts in the canyon, which will make your journey 0% more difficult.

Natural anchors abound. All obstacles below the pothole rappel yield easily to partner assists. Some are intimidating at first glance, but none are bolt-worthy.

Bring a headlamp.

Great time, low water level, ankle deep at most.

About half full of water. Not horribly cold. Replaced anchor at keeper. Everything else was awesome.

Wow what a fun canyon! Alcatraz is in soggy mode from recent moisture and upper-thigh deep water is unavoidable. There is one spot that is waist deep toward the end whose depth took one member by surprise (is stem-able). It was a cold day on the rim but very pleasant one in the canyon, no wetsuits used or needed. Semi-Keeper has shin deep water, defeated with pack toss and partner assist. Be careful on that lip, a fall over the other side would be possibly fatal. Two people were 200+lbs and fit with a little stemming, this canyon is way easier than Middle Lep. 3 people 4.5 hours.
