Halo, makers of various wheels and components, have entered the gravel market with three new models of tires. Their RXR (650b x 47mm) is an all-road/hardpack tire, GXR (650b x 47mm) is an all-surface tire, and the GXC (650b x 47mm or 700 x 38mm) is a gravel tire with lots of grip for the roughest days out on backcountry roads. Each tire comes in black or gumwall and you can find out more at Halo Wheels.
