Excavated Walrus Ivory Ice Cleat

This is a very old Eskimo carved ivory snow cleat.  It has tow large holes on the wide end for attachment and a large hole on the narrower end as well as two small holes next to it.  It looks like the large hole was done later as it overlaps part of one of the small holes.  It has a collection number, E 240, on the narrow end.

L. 3 3/8": W. at wide end 1 1/8"
