Jupiter River, Monday June 20 Immerain. Stormy wind and a heavy fog on and I am held up for the present. Left the Light and Mr. Lemieux at 10.45 and at 11.30 I was ashore on the east side of Jupiter river valley collecting a few snaphills and Pilceps in zone E 3. While I was collecting Priorer walked to the river mouth to see how to get in and by 12.30 we lifted anchor and are away for the river. In the afternoon collected at the high Jupiter River cliffs just over the river. The cliffs are near 150 feet high, the upper 70-80 feet being of the waterlume like limestone-shale holding a very sparse fauna and Onmograph- tus. The lower part of cliff is a soft shale contort mitricella fossils, zone E2, the upper being zone E3. Took 3 pictures of the cliffs on a clear day. Built 1/6.
