I live in LA and enjoy day hikes, backpacking, rock climbing, and mountaineering.

comment When is it too cold for Tarping?
I think of tarping mainly as a technique for ultralight summer backpacking. If you're in snow, a tent lets you keep everything dry. A tent will also keep the wind off your face while you sleep.

comment Dropping gear: Where did the hairline/micro fracture urban legend come from?
Are we talking about dropping a carabiner from waist height to the ground, or are we talking about dropping it 100 feet? I can't remember ever dropping a carabiner. Carabiners are what you use to prevent dropping other things.

comment Slings for anchoring and lanyard in rock climbing
Related: supertopo.com/climbers-forum/2542038/… The video is in French, which I understood only a little of, but the accompanying discussion seems to say that knotted dyneema can fail under a fall factor as low as 0.3.

comment Should I be using Dyneema slings for lead climbing anchors?
If I'm understanding the British HS correctly, then I guess it's about an American 5.6, i.e., vertical or near-vertical rock climbing where you need fixed belays for everything. Are the anchors you're talking about belay anchors, or just pieces of pro that you place during a lead?

You obviously put a lot of work into this answer, so thanks for your effort, but it isn't an answer to the question I asked. I asked a very specific question, and this is a completely general discussion of how to give a belay.

comment Tips for camping in the territory of elephants
In East Africa, both elephants and water buffalo are hazards, and the advice I've heard was to avoid hiking in twilight. I think this is on the theory that you want to avoid surprising the animals by walking around a corner when they don't know you're there. In daylight they're more likely to see you coming, so they aren't taken by surprise. If you see a herd of water buffalo from a distance, keep your distance from them.

comment How to make a fully-enclosed tarp setup with a 1.4 x 2.4 meter tarp, for one person?
There are many, many different ways to set up a tarp. Every time I set one up, it ends up different. It depends on what trees and rocks I have handy.

@WedaPashi: :-) The cultural touchstone that will only work for Americans is that it was like the Charlie Brown Christmas tree.

comment What is the first thing to do, when buried in an avalanche?
Your focus is on the wrong thing. You should be focused on how not to be in an area where an avalanche is likely. This can be done by examining a topo map and checking how much recent snowfall there has been. Once you've been buried in an avalanche, your chances of survival are extremely poor no matter what you do.

comment What equipment do I need as a beginner outdoor rock climber?
People typically only own one harness, one belay device, and one helmet, so they aren't going to be able to loan that stuff to a climbing partner.

comment Slings for anchoring and lanyard in rock climbing
The DMM links are really good, and surprised me about a lot of things. I didn't know that it was possible to break a knotted, shoulder-length sling with a fall-factor-1 fall equal to the length of the sling -- scary!
