Sunday Jan 17 - 1926. In the afternoon Paul T. Leashaer took me in his car northeast towards Mt. Bonnell beside the Colorado River. We began to collect about 8 miles south of Austin in the Comanchian, may be in the Walnut Clay, high up on the cliffs facing the river. Here are got a fair total and about 18 specimens of a little regular echini, and one Hlee type - like irregular echini. Further down the long descent of the road, may be 25 to 30 furlongs down, are got more totalies and in a then gone a lot of calcareous algae reminding of Paserulus. Also one Hlee typus. Then down the cliffs to the level of Bull Creek There another little new groups Mr. This is about 1 1/4 miles above the mouth of Bull Creek into the Colorado River. This so in the Glenrose formation, Here we saw a gone less than me foot thick composed of Articulina. Here also reign the Paserulus like algae. Notably can than 10 feet down down are collected Reguenda that made a gone 6 to 20 inches thick. The Glenrose here is an alternation of soft and hard limestone; the joints come in the softer goes.
