Stone slab in east-central California used to grind acorns. In archaeology, a grinding slab is a ground stone artifact generally used to grind plant materials into usable size, though some slabs were used to shape other ground stone artifacts. [1] Some grinding stones are portable; others are not and, in fact, may be part of a stone outcropping.
Weight is disputed; a 2006 analysis estimated the depth of this stone at only 1.8–2.5 m, for a weight of 250–300 t. [32] Weight formerly said to be 550 to 600 t.

In the latter case, orthostats are large thin slabs of gypsum neatly and carefully formed, for use as a wall-facing secured by metal fixings and carrying reliefs, which were then painted.

One of the world's hardest slab climbs was The Meltdown 9a (5.14d), a 1980s Dawes project in Twll Mawr, that was only climbed by James Mchaffie in 2012. [11] By 2024, it was joined by the two 9b (5.15b) graded slab-routes of Cryptography (in Switzerland) and Disbelief (in Canada), as well as the neighboring line of The Dewin Stone at 9a+ (5.15a).
