| St. Gassies, Francois | 29 | Not recorded | Not recorded | Not recorded |
Five cavers were exploring in a lava cave of the Gaping Holes Lava System east of Mt. Shasta in northern California. At the apparent end of a breakdown pile, Francois St. Gassies (29) was climbing down an inviting hole when, with a rumbling sound, the breakdown shifted, burying him. He was soon freed by his companions. As one caver pointed out, lava rocks are porous and thus not as heavy as limestone or marble.
As Wolff points out, if it looks unstable, maybe it really is.
