NO. 2 MISSOURI VALLEY DEVELOPMENT PROGRAM — WEDEL 37 



From May 2 to May 8 Dr. White visited seven proposed reservoir 

 areas in the Lower Platte Basin in north-central Nebraska, including 

 Amherst, Brewster, Buffalo Creek, Cairo, Ericson, Mullen, and 

 Rockville. Fossil remains were found only in Mullen, and these were 

 reworked material of no scientific interest. On May 13, a recon- 

 naissance of the Smoky Hill and Republican Basins in southwestern 

 Nebraska, northern Kansas, and northeastern Colorado was begun ; 

 by June 6, 19 reservoirs had been visited. These included Beaver 

 City, Buffalo Creek, Culbertson, Enders, Harlan County, Medicine 

 Creek, Rock Creek, and Red Willow Nos. i and 2, in Nebraska; 

 Cedar Bluff, Glen Elder, Kanopolis, Kirwin, Norton, Pioneer, 

 Webster, and Wilson, in Kansas ; and Bonny and Wray, in Colorado. 

 On the basis of material seen and the exposures available, more ex- 

 tended investigations were recommended for Beaver City, Bonny, 

 Cedar Bluff, Enders, Harlan County, Medicine Creek, and Red 

 Willow Nos. I and 2. 



From June 13 to June 28 Dr. White examined the proposed Glendo 

 Reservoir area in the North Platte Basin in Wyoming ; Angostura 

 and Deerfield in South Dakota, and Edgemont and Keyhole in Wyo- 

 ming, all in the Cheyenne River Basin; Bixby and Green Grass, in 

 the Moreau River Basin, and Blue Horse and Shadehill, in the Grand 

 River Basin, all in South Dakota; Dickinson and Heart Butte, in 

 the Heart River Basin, Cannon Ball in the Cannonball Basin, and 

 Broncho, on the Knife River, all in North Dakota. Further work 

 was recommended at Edgemont and Blue Plorse. For most of the 

 others, suitable geologic exposures were lacking, or the formations 

 involved are much better exposed outside the proposed reservoir areas. 



Between July 12 and 31 the following proposed reservoir projects 

 in Wyoming and Montana were visited : Kortes, Onion Flat, Soral 

 Creek, Du Noir, Boysen, Anchor, Badwater, Oregon Basin, Kane, 

 Red Gulch, South Fork, Bull Creek, Triangle Park, Lake Solitude, 

 Smith, Willow Park, and Middle Fork, in Wyoming; Little Horn, 

 in Montana ; and Yellowtail and Moorhead, each of which lies partially 

 in both States. Anchor, Badwater, Boysen, Middle Fork, and Moor- 

 head should be revisited for more intensive investigation. 



From August 9 to September 25 the paleontological survey was 

 extended to the following localities : Crosby, Jamestown, Sheyenne, 

 and Souris, in North Dakota ; Medicine Lake, Sunlight, Thief Creek, 

 Hunter Mountain, Taylor, Bridger, Mission, Sweetgrass, Antelope, 

 Newland, Stanford, Hobson, Ross, Snowy, Tiber, Wilson, Nilan, 

 Wells, Canyon Ferry, Terry, Whitetail, Apex, Kelley, Clark Canyon, 

 Brenner, and Landon, in Montana. Of these. Medicine Lake, Sun-
