Slick bouldering on mossy rocks

Hemet while bouldering seldom seen but I do it on highballs. I like my brain.

yah, I admit I had it on yet from taking a closer shot of stickers for the sticker-page. Forgot to take it off, but this loose limestone falls alot too.

Ya Limestone does. It's all limestone here and I hate it.

Years ago when I climbed at that place about twice a week, I noticed how bad my fingertips were peeling off due to the simple acids made of sweat and limey rock. I never had that happen on granite or sandstone.

Limestone with water does eat skin.

yes it does Bex. water, sweat forms a weak carbonic acid from the CaCO3 in the limestone. Just enough to beat up fingertips after a long day with no tape. Weak, but it does something.

I forgot what acid it made. I knew it made an acid, it's what causes the Kearst landscapes of Cambodia and Vietnam. Humid climates and limestone bedrock.

Yes, Karst topography, caves and all that good limestone stuff. Pretty sure it's carbonic, or weak HCl if lots of chlorine present in mineral content.

yep.
