"Perfect day to do 5 peaks. Etiwanda, Cucamonga, Bighorn, Ontario and Sugarloaf. Better known as ECBOS. What a great and challenging loop this was. Started out early at Icehouse Canyon and headed straight to Icehouse Saddle and then to Etiwanda Peak. From Etiwanda it was a short traverse off trail along the ridge to Cucamonga Peak. From Cucamonga Peak I followed the trail down to Cucamonga Saddle and then up a trace trail about a half mile and 700 feet in gain to Bighorn. From Bighorn it was a simple following of the ridgeline to Ontario Peak and then down from Ontario to a point between Cherry Canyon (left and Falling Rock Canyon (right), I followed that spur down to a saddle and then up to Sugarloaf Peak. From Sugarloaf, it was a half mile back down to the saddle and then the big descent down Falling Rock Canyon. It was my first descent down Falling Rock Canyon and it didn't disappoint. Tough, steep, but a fun descent down scree fields and some class 3 bouldering." — Philip-Yoho • May 25, 2019

"Sweeping Icehouse Canyon. Ending up liking his bump quite a bit. First the fun class 2 tracing the ridge from Ontario. Then on the way down sustained scree skiing!!!! I just wouldn't want to climb up from Icehouse Canyon." — JustinB • Oct 1, 2018

"Familiar story on my part. I only had 5 consecutive hours to bag a peak for the entire weekend, and I end up with an HPS summit. I had considered Sugarloaf in the past, but always avoided it since it would involve a lot of scrambling. Today I didn't seem to mind a good scramble. After leaving the Icehouse Canyon Trail at about a half mile in, I crossed the creek and began ascending Falling Rock Canyon. It didn't take long to realize and contribute to the canyon's name. I methodically worked my way up to the ridgeline leading to Sugarloaf and then to the summit. Coming back down was much quicker. I scree skied back down to the creek channel route in the canyon before descending to Icehouse Canyon and concluding the visit. Had many opportunities to fall or to turn an ankle, but it never happened. A good half-day in the mountains!" — MikeTeeples • Mar 31, 2018

"A perfect short morning hike up Falling rock to Suagrloaf peak. Fun company and perfect weather. The valley was a sea of clouds but we had great views of Mt. Baldy and the 3 T's!" — DerekJayRichardson • Apr 20, 2015

"Bagged it on the way down from Ontario Peak. Watch out for the last dry waterfall! It's not passable. To detour this, get on a trace trail on the east side, then contour to the east. " — thesearcherextraordinaire • May 17, 2014

"Was surprised by the two dry falls early, but once you got past those it was pretty standrad class II. Found a wedding ring during the hike, although since only one other person has claimed it before me on this site, I don't think it belongs to a peakery member." — Christopher • Jan 20, 2012

"Went on a day hike to Bag Bighorn, Ontario, and then cross country down to sugarloaf. All went well until we decided to cross country down sugarloaf to the Parking lot. Instead of going down falling rock canyon we went straight down the north face. It was very steep loose rock and quite dangerous but we managed fine until we got about halfway down and hit in passable buckthorn trees on both sides... At this point the sun was going down, my hiking partner was fatigued and our way out from here was to climb back straight up this steep loose rock in the dark which I knew would be very dangerous especially with her fatigued, and then cross country back to Ontario in the dark, and hike all the way back to Icehouse saddle and down Icehouse in the dark. Or we could have climbed back up the loose steep rock to the summit of sugarloaf and made our way down falling rock canyon in the dark. All these options were too dangerous for me to consider without daylight. So on a nice weather night we stayed the night under the stars on a big flat granite rock, the only big flat rock in that entire area we were stuck in. When we looked around we realized if it wasn't for this rock it would be one shit..." — 1-with-Nature • Sep 5, 2010
