Boundary was completely dry, no one else there. Was nice and cool during heatwave. 56F start at 7am then 70s-80s rest of day.

First rap has three drop-in points. Did tree by trail, it was 130' but can be done in 2 stages. Don't recall which rap but bolt was removed, built anchor off a wedged log.

Kolob creek was flowing with ankle deep water but one part was mid-thigh. Several deep pools for swimming but they can be bypassed.

MIA exit is a beast. Got stung trying to get past hornet nest in middle of uphill trail, backtracked and took steep bypass left of dry fall which connected back to main trail out.

Canyon is completely dry except for one puddle at the bottom is one rappel. Kolob creek was about ankle deep as only 3 cfs were being released from reservoir. No problems and a great time!

Still flowing! Anchors weren't in the best shape and some were built incorrectly. With the running water, two down-climbs became rappels. Kolob was running around 35 CFS and was completely manageable.

Group of 6 did Boundary Aug 14, 2019. Clear weather for the week. Washington Co water conservatory reported 3 CFS discharge and added “ we do NOT rec’ that you do Boundary bc of heavy snow melt”. This is 100% bad info from them. Worse than no info at all bc they are wrong simply to CYA. Pissed me off. None of the 6 of us wore the wetsuits we each carried through the entire canyon and up MIA. 2” stream entered canyon. Tiny amount of spray on rappel only. Kolob creek had 2-3 short mid chest wades and otherwise was ankle deep ( less than Narrows was this week). Anchors were good. We accidently took an “alt” route up MIA passing high and to RUC of the Saddle up a steeper section to where we hit a road on the top. Followed it out. No problem.

Take home : use the phone line for Kolob Res. release CFS value only. Totally disregard whatever else their secretary has to add.

Flow rate reported at 3 CFS. Water was flowing consistently through the raps in canyon, but at a level that made it a lot of fun. We were all wearing wetsuits. I was wearing 2mm, and was a bit chilly a couple times. Those with 3+ were fine. Kolob Creek had a lot of trout in it, with water level mostly below knee-deep. There was one pool in Kolob Creek that was a bit deeper and went up about chest high. No swimmers. All anchors were in good condition. We used everything that was already in place. Our group of 4 took about 11 hours round trip. We were making good time until we hit MIA which slowed us down considerably. We likely took a steeper route than was necessary.

Very heavy flow in the canyon. Last year, when it was dry, it took about 1.5 hours in the canyon. This time it took almost 3. We wore 5/4 wetsuits, 3 mm booties, and 3 mm gloves and were mostly comfortable except for our feet. All of the anchors were in good shape. The flow in Kolob creek was very fast, with white water in many places. There was only one area where there was a required swim. The water level was generally knee to thigh deep. It took our group of two about two hours in the creek before reaching the MIA. Compared to all the work we had to do to get us to the MIA, the hike up it wasn’t that bad! Overall, great time and totally worth it as long as you’re prepared.

We spent the night before camped up on the plateau (temp bottomed in the mid-teens). Called Kolob Reservoir for outflow, and learned the whole thing was drained dry earlier in the year. The canyon was pretty dry. We left our wetsuits in the truck.

Bone dry till Kolob, then plenty of wades to make us almost regret our wetsuit decision. Multiple wades wet us up to mid-calf, and slowed us down some. We arrived at one that would've been about a 20' swimmer for sure. But just then another party in drysuits arrived and did us a major favor by shoving in a second downed tree that allowed us to cross totally dry.

Anchors were in great shape. Our party of two ran the canyon with one 200' and one 120' rope at a fairly easy pace from about 730am to about 330pm. Dressed in thin thermals, hiking pants, approach shoes, rubber-palmed knit gloves, and light down jackets, and we were both comfortable.

Bone dry, drug wet suits through for nothing. A coupe of waist deep waders in Kolob creek.

Boundary completely dry, no water in the canyon at all. Water in Oak Creek was never deeper than mid-thigh. Mild weather. Did not use a wetsuit. All anchors in good condition.

Dry. Anchors in good shape. Mia exit in good shape. Fun day.

No water flow in the canyon on Thursday. The spring is running strong at the headwaters. All anchors are good. My beta said that there was nothing over 100 feet for raps in the canyon but the first rap (using the large tree on the south side) going down to the site of Rap 2 was about 125'. I did install W&R in a pothole that's on the way down so now that rap can be done in two parts with less than a 100' rope. When exiting up the MIA, be aware that there is now a track in a sandy section above the dry fall that leads away from the correct trail. It's possible to get up to the road that leads back to Pipe Spring (now posted as not safe for drinking) going this route but it's not a good idea. Stay within 20 meters or less of the south wall of the canyon as you go up until you get up closer to the 3 snags (dead trees) at the top of the route and you won't go off course. I would give this a 5 but the MIA exit isn't much fun.

Boundary is trickling with maybe 0.5 cfs flow throughout the canyon. Water was up to knee deep in the technical section and up to chest deep in Kolob. Two big cairns marking the turnoff from the creek up the MIA. 10.5 hours from car-to-car for our group of 5. All anchors in good condition; webbing looked new.

Boundary is completely dry and still so pretty. We enjoyed the canyon from start to finish. All the anchors were in good shape although we beefed up one anchor off a smallish boulder with extra boulders to make sure it would stay secure. The walk down Kolob Creek is such a treat! One chest-deep and one thigh-deep wade down to the MIA trail. Water is very clean with lots of trout in the creek. Flow was very gentle, maybe 2 cfs. Two cairns mark the turnoff to the MIA. Took us 2 hours to take the trail from the creek up to the road, moving slowly and route finding. Pipe Spring was flowing clear and cold and made a nice spot for a break. Total 10 hours car-to-car from the West Rim Trailhead. Great day!!

No flow. Almost dry within. Anchors in good shape.

Canyon didnt have any water so no wetsuits required. We hit water once we reached Kolob and had a couple very short swims.

I thought this canyon was just ok. Without water, this canyon is a very average Zion canyon. The MIA hike out is miserable! I think water flowing through the canyon would make it much more fun.

A great canyon, some spectacular photos, and all the anchors were in great condition. The MIA trail was also in much better shape and better defined than the last time I went 2 years ago.

The reason I gave it a 4 and not a 5 is I hate with a passion river walking (theres about 20-30 min of it from the end of boundary to the MIA exit) and the canyon itself isn't that long for work needed to exit afterwards. Definitely not enough that you should stay away, but for me it knocks a star off.

No flow. No wetsuits for me or my kids. MIA in excellent condition.

Completely dry down to Kolob Creek. 3 cfs from there on, pools up to your nips and pretty cold but not unbearable. No wetsuits needed.

Approach hike dry and dusty. The technical section completely dry except for a couple potholes with a bit of snow. There was a trickle of water running in Kolob at the confluence but dry at the MIA exit. The exit was easy to follow for first timers. 9 hours total for a group of 6.

Boundary was dry, getting into Kolob, there was a fair amount of water is at what I would estimate 3-4 cfs. No swims in Kolob, but there is a couple of really deep areas. Nothing unusual encountered. Lots of beauty, lots of fun.
