"1.19.24~The Sentinel {X5}~ 8 miles, 1,600’ gain in 3:16hrs. I just took it easy since I was tired. Saw wild hoses and sheep. Warm Winter day https://www.facebook.com/share/r/snG3VKoicwtHqt5u/?mibextid=WC7FNe" — paula.raimondi • Jan 19, 2024

"We took a modified ascent and descent route. I had always wondered about going up or down the face of the mountain...and we came down it. The descent route that we took was almost entirely sandstone...much better than the loose gully route. It saved about a half a mile and just over a half hour...even with route finding. Definitely a route that I would do again. The track that I included is a little off course at the beginning. If using it, follow the old jeep trail and not the wash at the beginning of the track (use the return route)." — Heartattackbruce • Dec 17, 2022

"12.15.19~The Sentinel (#3) aka Rainbow (3,209’) LMNRA w/Jimmy. 8 miles, 1,800’ gain in 3:37hr. (to the peak in 1:46hrs.) We left the comforts of civilization for a morning of exciting, thrilling and satisfying wilderness trekking only The Sentinel can deliver. This is one of the top routes and peaks in this area. It has everything, historic Jeep trail, scenic valleys, Aztec Sandstone surfing, scrambling/climbing, sheep trail traverses and knifes edge ridge surfing on carnivorous limestone. The scenic views of the chaotic landscape are mind blowing! Fun 🥰🌻🤗 @ " — paula.raimondi • Dec 15, 2019

"11.1.18~The Sentinel. Happy November. The chilly morning made me crave the warmth of the desert. I made quick work of this trek while the kids were at school. In my opinion, it’s one of the most beautiful, thrilling, challenging, scenic and rarely visited Summits in the LMNRA. This remote area gives you complete solitude, unique expansive views of Lake Mead and is very close to home. The route crosses into the stunning Pinto Valley that has spectacular outcrops of Sandstone structures decorating the landscape. At the base of the mountain you enter a gully with sandstone towering above you as you climb. You wind through washes and dry falls hidden in the mountain. You reach the ridge then travel along thin sheep trails etched into the steeply angled mountain slabs. I worked my way up the steep slabs to the main summit ridge and traversed along (the semi-knifes edge) to get to the summit. This is my second time doing this peak and while it is very challenging, I found this time was easier and less frightening since I’ve become more experienced. Only one other person is listed in the summit log since last being here nearly 2 years ago. 8.5 miles total, 1,600’ gain. On the top in 1:35h..." — paula.raimondi • Nov 1, 2018

"SENTINEL Peak 2-24-17(solo)...I've heard this it the must do Peak in The Lake Mead NRA. It did not Disappoint. Very pretty landscape with outcrops of red sandstone. What an adrenaline rush! I used Harlans GPS Trax (thank you) and studied Bob Spirko's trip report so I felt confident. I parked off Northshore road and set out across the Pinto Valley to a drainage that led up to a ridge. From there I followed sheep trails along a precipitous ridge until I found an area to make the final ascent. The last part took me an hour of hesitation and going up and down different parts trying for the safest way. It was scary and steep but I was able to find a horizontal ledge to traverse to get some relief from the vertigo. I'm really proud of this Summit. I applied all The things Harlan and other pals have taught me. " — paula.raimondi • Feb 24, 2017

"Amazingly, this was the last time that I hiked with MJ. It was bitterly cold, and she said she would have killed me if I showed up in shorts. Did a short rap instead of the traverse, following Nick Nelsons loop." — hwstock • Feb 3, 2016

"I had heard great things about this mountain, so I decided it was time to finally do it! The hike is definitely one of the best around Lake Mead! We were in the clouds for a good portion of the way up & at the top, so our view wasn't great. I guess that means I'll just have to go back!" — Kevin • Dec 20, 2014

"This pretty much goes down as one of the best desert summits I have climbed. Excellent class 2/3 route ascent from the northeast, followed by a crazy class ~3 canyon descent (with optional rappel) on the west side. Absolutely fantastic scrambling and views! Pics to be added..." — calipidder • Nov 27, 2013

"Well, this was my birthday & one I'll never forget! I got a late start, didn't get out there until around 11:30am. Ran into some folks in Pinto Valley & chatted with them for a little. I had been up most of the route, so made good time up the red canyon to the sheep path. From there, I couldn't figure out how to get over to the limestone ramp. It never occurred to me to go up! Instead, I dropped all the way down below the lip of the ridge & re-ascended which added lots of time. Made it up & was shocked at how late it was. Tried to go down a shortcut & wound up getting cliffed out & had to ascend...again! By this time, it was getting dark. As I descended the limestone ramp, I slipped & fell, sliding on the sharp limestone for several feet. It completely tore my pants to shreds & my entire backside was sliced up. I couldn't sit or lay on my back for several days (no exaggeration!) It was extremely painful. So, I panicked from that point & dropped all the way down into the wash. It was completely dark at this point...no moon & heavy cloud cover. I hiked back up the wash, trying to stay close to my GPS tracks up above on the ridge. My headlamp was also failing. I could only see 2-3 fee..." — StudioHoodoo • Jan 17, 2010

"Nick N brought this peak to my attention; it used to be called Ragged Peak by the Booths, and Rainbow by Lee Schultz. Ed Forkos gave it the name "The Sentinel" ca. 2002. Below is the old way in in-- most people now take a much easier trip from Redstone. https://hwstock.org/sent/" — hwstock • Jan 16, 2005
