A fine example of 'glendonite', which
is a calcite replacement (pseudomorph) of ikaite. Ikaite
is a calcium carbonate hydrate - CaCO3 ยท6H 2 O,
which dehydrates to calcite - CaCO3
above 8oC. This sharp, doubly terminated
example looks like some sort of blowgun dart with fins. A
superb example for the species/locality.
