trains for Boulder and Eaton to see the Fourth of July celebration. Now 8:30 a.m. and Markman is just dressing while Harry is still in bed. We had the cots again which we left in Greeley on our way north two weeks ago. Packed for shipment some of the outfit which we will not need again and left Greeley at noon, passing through Evans , then crossing Platte to east side, recrossing to west side about 7 miles from Evans at the Twin Bridge . We camped at 4:30 on Big Thompson (S. side), two or three miles below mouth of Little Thompson . While Dodds and Markman made a dry camp in a pasture, getting water from an nearby farm house, Harry and I started to examine the bluffs north of the creek, wading across. The formation is typical Fox Hills sandstone. Found Cardium speciosum , shark tooth and other fossil mollusks at base of exposure. Near the top I found fossil leaves which I at first took for Laramie species
