Two shell masks from Montana.

   The shell masks pictured above are casts of two that were found together in a small cave in Montana.

   In the fall of 1992 two Canadian campers discovered two rare marine shell mask gorgets in a small damp cave in Montana. This cave is located in rugged terrain and on public lands. The two campers reported their find on the National Geographic Hotline soon after the discovery. National Geographic then reported it to the Montana State Historic Preservation Office who in turn contacted the Bureau of Land Management. Native American groups were also contacted and consulted before and after the official recovery of the artifacts began.  Representatives from at least two of these agencies accompanied the discoverers back to the find site.

   These two marine shell masks were found in a cave on public land in the fall of 1992. They appear to have been made from the outer whorl of a large marine shell, probably a whelk. One of the masks has a nicely done carved image of a face and the other is a fairly simple design. Both have several holes drilled in them and red ochre smeared on the back.

     Although rare, the majority of all shell masks have been found in the east and southeastern U.S. in the states of Tennessee, Arkansas, Kentucky, Ohio, Illinois, Iowa, West Virginia, Alabama and Georgia. The two masks from Montana are the most westerly reported finds and they are the only ones ever found in Montana. Manitoba is the farthest north that shell masks have be reported. So they are very widely spread over an area covering thousands of miles.

   This shell mask is the better of the two examples from Montana. The carving is very well done and the shell itself is surprisingly well preserved. It has a mouth that is carved in relief and there seems to be a hair or scalp line that has been delineated with a groove engraved along the upper wider edge. Some of the features like the long narrow nose and the two perforated eyes are similar to the masks from South Dakota. Both of the Montana masks have a large centrally located hole that is unknown on masks from the southeast. This one also has quite a lot of red ochre on the back and some of it seems to have been applied with finger tips. There is also some brown staining around the left eye that is suspected to be a mastic (tree resin used as an adhesive) that may have been used to attach feathers of other decorations to the mask. This mask measures 6 1/2 inches (16.5 cm) long.

   Only one of the shell masks from Montana is carved with a full and obvious facial design. That one has a long narrow nose and two perforated eyes that are similar to the two shell masks from South Dakota. This mask also has a mouth with lips carved in relief. A feature that is unique to both of the Montana masks is the single large hole in their center. It's a design that is unknown on masks from the southeast. Both masks also have many more holes drilled in them than the South Dakota masks and that's also a feature not seen on most shell masks from the southeast. The mask with the face has a total of nine drilled holes and the plain mask has six holes.

   Both of the Montana shell masks have red ochre smeared on the back. They have a pattern of red ochre staining that appears to have been applied with finger tips along the back edge. The above picture shows some of the red ochre and where it was applied to the back edge.

    Both of the Montana masks were heavily stained with red ochre on their inside surfaces. The pigment was applied in a similar way on both of them. Red  patches were "painted" along the inside edges with what appears to have been the persons finger tips. Dr. Tom Roll of Montana State University took samples of the red ochre for carbon dating after suggesting that it may contain an organic carrier suitable for testing. Dr. Marvin Rowe of Texas A&M also took samples of the ochre. At the time of printing one reliable date had been retrieved from a shell sample taken by Dr. Rowe placing it somewhere between 1411 and 1481 A.D.

   This marine shell mask does not have very good facial features. The maker seems to have had a more stylized version of a face in mind. It does have a long narrow nose carved in relief and two    perforated  holes for eyes. There is also a step design cut out on the  edge that gives the upper area more space to represent the hair and ears. This mask has a considerable amount of red ochre smeared on the back. Some of which seems to have been applied with finger tips. The bare patches are areas where red ochre samples were taken for lab analysis. It measures 6 5/16 inches (16 cm) long and 6 3/8 inches (16.2 cm) wide.

   The other shell mask from Montana is in poorer condition and has fewer facial features. It seems to have been the intention of the maker to design a more stylized version of a face. Like the other three masks from South Dakota and the other one from Montana this one also has a long narrow nose that is carved in relief and two perforated eyes. There is also a notched step design carved on the edge that forms a wider area on the upper half where the ears and hair would be and a narrower area at the bottom where the chin would be.

   The second Montana mask, the one with fewer facial features, is unique from the others in that is has a design engraved all around the edge. The design is a series of vertical lines that are spaced approximately 1/16 to 1/8 of an inch wide.

   The cave where the Montana masks were found is believed to have been an important spiritual site for northern Plains groups. The fact that the walls were partially smeared with red ochre, the discovery of two shell mask gorgets, the absence of stone debitage or complete projectile points are good indicators that strongly suggest that the Montana masks may have been spirit offerings left there by one of the Plains tribes. In the case of the South Dakota masks, one of them was found on Bear Butte which is considered to be a sacred location by many Plains groups. The other mask was also found on a significant landmark. Local Lakota beliefs indicate that the South Dakota shell masks may have been used in curing ceremonies.

   Samples of red ochre were scraped off this Montana mask for lab analysis.

    Nothing has been found that would indicate that any of the shell masks from either Montana or South Dakota were associated with a grave. Plans for further investigation of the Montana site was objected to by the Native American tribal representatives and no further excavations are planned.
