Default Re: Red Mountain or Century BSR

Links placed between [img] tags must end in the image filename. Tags removed, links active.

BSR breaks down basically like so:
Large spouts, crude markings = RM
Small spouts, number and pattern letter not crude = early automation RM or Century
Small spouts, dimensional markings = DISA automation Century
