Featured Another Inuit? Carving this time in Pumice?

Thanks guys!!

 

Ahh thanks, I was wondering why I wasn't finding anything quite like the OP's carvings listed as baleen.

 

Think of bone or antler marrow...like the kind at the top Of Mr.London's avatar...& then think WHALE SIZED !!

 

Did u see the pic of the Baleen boat I posted ??

 

As mentioned above; whalebone, with baleen base. Baleen can be a bit difficult to identify until you have some experience with it; larger pieces may have an attractive fringe; smaller pieces may look like wood or horn.
Bugs really like to eat it, so the appearance of small tunnel-like chewed areas is almost diagnostic. The harvest and preparation of baleen is an interesting - also smelly and messy - process.
In addition to the baleen boats, you'll see pieces with etched drawings; and used as decorative elements or bases in other carvings.
Don't ship your item across the US/Canadian border and you should be OK.
