Sep. 25-1909, Saturday. Took the 7.20 A.M. train on Missouri Pacific for Fern Glen. Got off at Valley Park about 2 1/2 miles east of Fern Glen. Between these two places one sees cliffs of oolitic limestone with small chert. From the grass of which is are almost none I take the horizon time about Burlington. At Fern Glen, pic-one place just north of the Flag station there's a little cliff of crinoid limestone at the track. Then just higher comes in a zone of red shale yielding the fossils collected these red shales pass into greenish and then gillium shale that at the top have small pebbles. This shale thick ones may be 20 feet and is the typical Fern Glen formation. Above in the cliffs many 75-100 feet higher are what we refer to as the Burlington. Long walk along the railroad and in front of the Castlewood Flag station we see the rims- onich that at this place contains chert. Less than 1/4 mile north are quarries and a lime kiln, in lower beds of the Limestone.
