husband leading our first lead climb up the Trough...

Big Rock is currently closed to climbing.



At the center of the larger portion of the Big Rock face, lies a water streak. The Trough runs straight up this, via several bolts. Picnic tables for the area sit directly underneath. Crux comes after the first bolt, with the balance of the route having copious amounts of hand and feet holds. Generous bolts protect this fun climb.


8 bolts. Can be done in one stretch pitch with a long rope, or done in two with a 165' rope. Belay anchors are found midway, 3/4 the way, and at the top just left.

The midway anchor is gone, but the climb is easily done to the top in one pitch. This route seems to have gotten more slippery over the years and now seem harder than the nearby Africa Flake route.

I was there yesterday (2.21.06), and the midway anchor is there, and quite fresh I might add.

this is a bolted sport climb, not trad

Very slipery, especially in the morning before the sun dries it off...
There is usually a top-rope hanging from the bolt/rap station as this is a favorite with groups...

I was unimpressed. The rock is very slick, indeed.

I soloed this on a day that I thought I was a real bad man...yeah...I'm dumb. Easy, but I scared myself up high. A perfect first lead for someone who has some experience already.

The chains are still intact at the midway anchor but one of the rap rings is missing. You can safely thread a 10.5mm rope through the one rap ring but if anyone wants to replace the second ring it would be appreciated considering this is one of most heavily used routes at Big Rock, especially among those with little experience.

I did it two days ago and really liked it! It was my first lead as well.

Are the anchors at the bucket the 3/4 or top anchors?

If you can lead 5.5, you can lead this route. This route is easy. Don't believe all the nonsense here up-rating this fun beginner route.

This was my first sport lead and I still enjoy it altough it is really greasy. And by the way, there is know way this thing is more than a 5.5

A couple of fun mantles. Forgettable except for the greasiness. I stayed in middle of the stain. May be easier and more enjoyable on the edges.

Fun climb. It's easier if you stay away from the dark area since it's slippery. I suggest climbing to the right for more grippy holds. You'll also be climbing right under the bolts.

Some of those holds are like trying to wrastle with a greased pig

I remember my fist time climbing the Trough in the 70's and watching Lynn Hill climbing next to me as her sister belayed her. I have climb for years at Big Rocks and still miss climbing the Trough and all the other routes at Big Rocks. A stepping stone for Tahquitz. Yes to be young again !
