What type of heated rock is best for cold weather climbing?

Recently I have been climbing routes and my hands are going numb. I heard someone talking at the crag the other day about heating a rock on a small stove and dropping it in their chalk bag. While they are climbing the rock stays warm and will warm your hand up so you don't go numb. I thought this was a genius idea but I began to wonder what type of rock is the best? Ideally you would want a rock that had excellent heat retention to weight. I think some sort of volcanic rock would be the best. Maybe a Granite type would be better? And while we are talking about rocks I thought these heated rocks could double for wiping your ass after a hard burn on your project. So the rock needs to retain heat as well as feel nice on your ass when wiping. Any thoughts?

Thank you. I will now go to work with a smile.

I usually microwave my shoes for three minutes before I climb on cold days. There - that's almost as dumb as the rock idea.

I haven't thought of the rock thing, but I know plenty of people who throw a hand warmer in the chalk bag.

I'm not sure about what rock is best to keep your hands warm. I have had luck with rocks in Maple but have also burnt a hole in my chalk bag. As far as wiping your ass goes I prefer a nice round rock but not too round as to not be able to get deep in there to clean it properly. Again Maple Canon is good place for ass wiping rocks as well. Try to stay away from sandstone because it leaves sand up your butt.

Oh for the love of God! Go get yourself some Hot Hands Hand Warmers, tear the package open, shake for a few minutes, and put those in your chalk bag. They work just as well as those goddamned hot rocks and they won't burn the hell out of you or explode on the gas stove. They last for nearly 12 hours now and you won't have to keep reheating a stupid rock!

Now I can't say much on the topic of heated rocks, I generally stick to hand warmers for that. However, in my experience if I have to use rocks for the wiping of the ass I prefer nice smooth rounded river rocks. If you can get them out of a running stream they can also act as somewhat of a wet wipe.

As a geologist, I'd recommend a blowtorch and some mine tailings. Good for the hands and the lungs.

certainly not any rock found in Western Connecticut, this shit saps warmth like my job saps my spirit some days.

As someone who likes light gear I would recommend a handheld pencil torch and basalt to save on weight. as a bonus the basalt makes your ass extra smooth.

Looks like the OP has snagged a live one!

We all know heating rock over a flame is dangerous, not to mention too much hassle in this application. I prefer self-heating rocks, you know, the type that glows green in the dark and is a vital material to make things that goes “ka-booooom!” Problem is that it’s kind of hard to find rocks like that just laying around. But if I tell you where I get my glowing rocks from, I’ll have to kill you.

Sandstone and limestone tend to explode whenever I try to heat them up. Stick to the cobble type rocks. Also, smoother is better for the wiping rock, limestone is a bit sharp and tends to rip the skin.

If you use one of these

heated rock

then you won't have to heat it on the stove, you just need an extension cord.

HOT ROCKS are the Best. From my experience, a smallish rock about the 11 - 13 nut size will work great. Heat the rock on your stove let it cool for a bit about a minute the chuck it into your chalk bag.

Weight doesn’t really matter it weighs about 8 – 12 0z I’ve only used granite and lime stone but I’m sure all rock types work.

IMO I like hot rocks better than hand warmers because they produce way more heat than a hand warmer. It’s like a furnace for your chalk bag.

Heat rock for your chalk bag? How about a Heated chalk bag

What if you just heated up your chalk? It has a similar heat capacity to a rock by weight and the conductivity is probably similar. I've never tried this, but it seems to make sense. Definitely a much lower volumetric heat capacity than a rock, but it's light and going right onto your hand.

Dude, rocks aren't versatile enough. Just use your hand to wipe, and it'll be 98.6 degrees, surely enough to heat your cold hands.

I've seen the heated rock trick done a lot, I've never planned ahead well enough to carry a stove to the crag and try it myself. My gut feeling is that you should use whatever is on the ground.

I've wiped my ass a ton with rocks. I like an angular flat one, to scoop any dingleberries.
