The eleven sherds of _Belcher Ridged_ type (Fig. 10, G, H) are generally
thinner and darker than the Alto wares. Six are dark chocolate to black
on both surfaces and through the cores; the other five have light buff
to dark gray surfaces, four of these with black cores. One is bone
tempered, all others clay-grit. No rims are represented and the body
sherds are 3 to 5 mm. in wall thickness. Typically, the elevated ridges
are vertical.
