Canyons are inherently risky. Flash floods occur without notice on sunny days. Technical skills & surrounding topography knowledge required yet does not eliminate risk.
There was really a trail here once?
Warning: No trail in sections
I would recommend this trail (or lack thereof) to that masochistic someone looking for a challenge that has basically exhausted almost everything else on his/her list. I say this because although your ultimate goal, Willow Springs, may be really neat (I wouldn't know, I didn't make it), getting there is a bear to say the least. In other words, unless Willow Springs is really awesome, the coolness/effort factor was low. Although getting lost is a distinct possibility and taking careful note of landmarks along the way is recommended, the real reason I would rate this hike so difficult is simply the complete lack of any discernible trail and the completely overgrown vegetation. If as the old Geographic Survey topos indicate that there was a trail here, it has long since disappeared. My guess is that if there was once an established camp at Willow Springs, they accessed it mainly from the North out of the Massacre Grounds area.
The trail starts at West Boulder Saddle out of Carney Springs trailhead (see Dacite Super Loop). From the saddle I just basically continued straight ahead right down into the stream bed and followed it downstream (left) from there. Although workable, this approach caused much "head scratching" and some fairly heavy duty bouldering. Believe it or not, there are cairns to be seen. Basically when the route was obvious they were aplenty, but always had a way of disappearing when you really needed them. I'm being generous when I say that every so often a hint of what once was a trail would appear, only to beg the question of who ever else was insane enough to be down in this jungle.
Following my simple but arduous stream bed strategy (virtually all of it at varying heights above the right bank) I made it about 3/4 of the way to Willow Springs by my estimation (3.5 Hrs). Had time not been a factor, I probably could inched my way further along but there were no signs of things easing up at all.
On my return I learned of several improvements to my original route. #1. From W.Boulder Saddle don't go straight down into the creek basin. Instead, follow the Ridgeline trail to the West (left) for about a quarter mile. You will see several cairns with one down and to the right of the trail. This should basically line up with a large dead tree down in the creek bed. Head down at that point. #2. To avoid some radical bouldering, when you get to the point where you can see the creek starts to head around a corner to the North (right), instead of following it, climb the ridge above and to your right, go over it and down into another smaller creek bed. Follow that one until it merges and continue.
If I ever get desperate wondering what treasures lie at Willow Springs I may someday try it again. I just wish somebody else would do it first with a machete. It would actually be somewhat easier if the creek bed was dry, although not a free pass by any means. Unfortunately this creek does not lend itself to boulder hopping as do some others. My concern about going when it was dry would be the heat. I went on a cool day and it was still a bit close down in there.
So there you are. I'm sure everybody's all excited to go, but I didn't want to pull any punches either. Actually if anyone has done or does this hike to Willow Springs I would personally invite them to email me so I can first congratulate them and next find out what's really back in there.
