This topic is only for telling your stories about things being accidentally slipped or gotten into inaccesible hollows as fissures, fallen into cracks in glaciers or below snow patches, etc. There are other topics for things being forgotten on the ground, rocks, meadows, snow or other surfaces. Please do not use this thread for that.
I thought on creating this topic after my new mobile phone was blown by the wind, slipped up on a rock and finished getting in unobserved into a fissure. Luckily I could take it by introducing my arm in a crack below the rock. It only had a few scratches. On Veleta we left a cantine stopper fell between a 3-4 meters high very hard snow patch and rock, it was impossible to reach it.
