• Some parts of the enclosing limestone are coarsely crystalline with individual crystals up to 1.0 mm. in diameter. The coarser parts are highly fossiliferous, being composed largely of trilobite carapaces. Finer-grained limestone contains large gastropods, but few trilobites. A few simple conodonts have been obtained from the insoluble residue (formic acid), as well as one silicified articulate species and several inarticulate species of brachiopods. Some surfaces of the limestone weather moderate yellowish brown and from a dis- tance could be mistaken for weathered greenstone. Other surfaces weather light olive gray. On fresh surface the rock is medium gray. The complete lack of evidence for any contact metamorphism (Gilluly, 1957, oral communication) indicates that the fossiliferous carbonate sediments were deposited after the basalt pillows had cooled.
