Mystery Lake is full. Tiptoes and chin deep on the rdc side. A few other knee and thigh deep pools in the top half. Fantastic canyon.

Great day!!! Mystery is super dry; we didn't get our feet wet until the springs. That's a short swim, then there's a waist deep wade and a chest deep wade after that before the last rappel. Hit the springs rap right at 3:30pm and we were in full sun from the springs to the top of the last rap. Perfect timing (as I get cold easily and stayed toasty warm without a wetsuit, making this my favorite trip to Mystery so far!)

All anchors look good. We didn't have a wrench with us, but it would be worthwhile for someone to bring one through the canyon. There were 2 old/rusted quicklinks on anchors that had been replaced by new links so the old ones should be removed from the bolts. Thanks anyone for your public service. :-)

Great day. No wetsuits needed on our trip. The high that day was about 90F. All anchors seemed to be in good condition. Everything very green and beautiful!

The lake is absolutely dry. Aside from one or two small, foot-deep pools we couldn't bypass, there was no water until the first big rappel. The first big rappel does have a very short swim at the bottom. There is some water in the canyon after that point, but it is chest deep at the max. Water is flowing at low volume over the final rap.

In our group 4 of the 5 of us had wetsuits, which we put on before the final two raps. I can be done without wetsuits, but they were nice to have. The one guy in our group without the wetsuit got a little cold standing at the top of the final rap.

The "Death Gully" is absurdly steep, I hear there are two possible routes down, I think we took the harder of the two. The first slot section is bone dry, nothing but tiny minor pools after the left turn until the springs. The lake is completely gone, not even any mud. I would recommend putting on your wetsuit at the top of the the big 115 foot rappel into the pool, because I was very cold without it and had to put it on after swimming in the pool to complete the canyon without shivering. Fun canyon, although it was more strenuous than I expected from descriptions.

Little wet at the end, a few swimmers, no wetsuit needed.

Made a second round this year; the drive to East Mesa trail is doable by a compact car (Chevy Cruze did just fine) now.

Replaced webbing on two of the bolted anchors. Mystery lake is all but gone. Went from neck deep to nearly nothing in 29 days. Everything is nearly in full bloom!

Group of 4, including a stop at Observation Point, 5 1/2 hours from car to narrows. Fast trip.

Friend left pair of Oakleys on last rappel; love to get them back if recovered! Contact me on please.

-All anchors fine.

-Lake is knee-deep if staying close to LDC wall.

-No wetsuits, only neos; was a bit chilly, but this Viking runs hot, so you'd probably freeze... bring your rubber.

-6 people, 5 hours car to car

-The least attractive run through Mystery to date.

-10% of vegetation is starting to bud... give it another 3-4 weeks.

Excellent trip! The road to Observation trail was muddy and contained deep ruts (8-12"). High-clearance is recommended until it's graded. Otherwise you will need to a walk an additional mile to East Mesa Trailhead.

Death gully was mostly dry. Some patches of snow but maybe 3-4" deep. Some mud on death gully, but most is avoidable.

Most anchors in good shape. Replaced two webbings lengths.

Most raps except the last 3 all had a trickle of water running down them.

Mystery Lake is chest deep and cold. We wore wetsuits and were glad we had them.

6 people (2 noobs) took 7 hours. Death gully slowed us down a bit.

Lost 2 pairs of Oakleys on this trip!! Contact me on if found! Read more here:

Despite being told there was a lake, there was no lake. No water until the springs, then a bit chilly with no wetsuits.

Canyon remains bone dry. First three real repels all screwlinks were partially or completely open! Check them! Replaced one with an obvious threading problem. All webbing was in good condition. Careful getting rope stick on last repel; there are waaay too many screwlinks making it quite a mess even when choosing the newest one; rope was easily stuck. They were too tight to undo by hand and I did not have a tool to remove them. 2 people East Mesa route to narrows walkway 4.5 hours.

Despite recent rains of the false-start of monsoon, bone dry; absolutely no water until the springs.

First four raps entirely avoidable.

4 through, one with a jankle and another a noob, 5 hours car to car.

Also, a snake guards the raspberries; beware.

Mystery Lake completely dry. Anchors and webbing in good shape. Most seemed to be recently replaced. No log jams from last report. Mystery Springs is about 10 feet, unless you find the underwater ledge and then it's only waist deep. The subsequent pool is waist deep, and the following pool is a mandatory swimmer for 5 feet. 6 people (w/3 noobs) was 6 1/2 hours from car to car.

Perfect time to do this canyon. Short log soup in the middle that was fun and not a problem. The lake is completely avoidable and the water in Mystery springs is very refreshing and beautifully colored. It took us about 5 hours total from the East Mesa trail and back to Springdale with two people. Can't wait to do it again.

After a stormy Aug 1, the upper half of Mystery had a couple of waist and chest deep pools. Someone built a cairn anchor close to the end of the upper section. The anchor is not necessary, the drop is a downclimb and the anchor is shaky. Do not use it.

Lake/Damn middle section was super damp and with some ponds but all avoidable. Lower section was drier and more in line with typical conditions. Bottom of spring room rap was full and cold. Short awkward rap into pool had a new anchor with supper thin red webbing wrapped around a rock. Be careful with that anchor as the webbing comes loose easily. Better yet, just downclimb this drop on canyon right. Partner assist if necessary. All bolted stations were in good shape.

All anchors are in good shape. Mystery Lake was dry. Mystery Spring was deep and cold and a short swimmer - fortunately the log leaning up against the wall at the end of the rap is still there and makes for an easy disconnect.

The pool at the penultimate obstacle (awkward boulder rappel) was deep enough for our group to jump. But webbing is in place at the tree set back a bit.

We did not find the lost watch. Sorry.

One of my favorites- Mystery was a hoot.

Pretty much the same experience as Madzilla. Mostly wanted to post b/c one of the people in our group lost their white Polar M400 watch ($300) somewhere in the canyon and I let them know I'd throw out a shout in case anybody who reads this comes across it. Text me at four three five - 215-1769. Thanks!

The first section of Mystery was mostly dry, with a few ankle/knee deep pools and one short waist deep pool with log soup in it. Mystery Lake, if you cross on the right, is mid-thigh on a short person (me) and knee deep on my taller friend. Mystery Springs is a swimmer and the pool right after is a swimmer for about 15 feet as well. Water is cold!! All anchors in good condition. Webbing looked good for now but a couple are showing wear and may need replacing by the end of the season or if the canyon flashes, so bring extra just in case.

Mystery Lake is knee deep and stinky. The bottom of Mystery Spings is a swimmer, but so fun on a hot day. All anchors were in good shape.

Love Mystery! Took 4 in 5 1/2 hours from ERT. All anchors in great shape. Mostly snow-free on Death Gully (but don't need snow-spikes for the other parts, just be careful where you step). About ankle to calf-deep water at 2nd set of narrows at the bottom of each rap.

Mystery Lake, while hanging onto the right side),never got higher than below the crotch (i'm 6'0").

Mystery Springs is a swimmer, unless you use the "underwater ledge". And the two swimholes between the springs and the last rap are waist and chest deep (mandatory, no escaping this), respectively.
