ITINERARY 517 



We reached the mouth of Fontenelle Creek June 15. Here we found 

 several ranches that seem to be in a nourishing condition. One of 

 them furnishes batter for a number of the towns on the Union Pacific 

 Railroad. The valley of Green Biver throughout most of this portion of 

 its course is rather narrow and bordered with canon walls. There are, 

 however, several expansions of the valley, especially at the mouth of La 

 Barge Creek, and where White Clay, Bitter Boot, and Piney Creeks join 

 the Green. The latter of these creeks appears to have considerable 

 alluvial land of good quality along its course. There is scarcely any 

 limit to the grazing land in this vicinity, as the mesas are covered with 

 bunch grass. A very fair wagon-road, a portion of which is the old emi- 

 grant road, follows down the west side of Green Biver. 



Sublette's road crosses Green Biver near the mottth of La Barge 

 Creek, and crosses the Fontenelle about four miles above its mouth. It 

 then bears away from Green Biver, going to the southwest, to the head 

 of Crow Creek, one of the branches of Ham's Fork. 



We followed the Fontenelle to the east side of the Meridian Bidge, 

 which we crossed south of the Fontenelle Canon, and then camped on 

 the branch that comes through Absaroka Bidge. Between Meridian 

 Bidge and Absaroka Bidge there are lines of hogbacks that extend 

 north as far as La Barge Creek. These were named the Fontenelle 

 Hogbacks. They also extend southward, but are not quite so 'marked, 

 as the strata have not been so much eroded, owing to the fact that the 

 fold becomes gentler in that direction, and the beds did not reach so 

 great an elevation as they did farther north. 



From our camp on Fontenelle Creek we turned southward, west of 

 Meridian Bidge, to Crow Creek, and then crossed to the head of Slate 

 Creek. The latter stream was then followed to the Green. South of 

 Slate Creek beds of Bridger age are seen, forming buttes that are the 

 outliers of the Bridger areas that prevail so extensively farther south. 

 From the mouth of Slate Creek we followed Green Biver to the ferry, 

 where the road from South Pass crosses. From the ferry we turned 

 southward, arriving at Granger Station, on the Union Pacific Bailroad, 

 on the 22d of June. The Bridger Group prevails between Green Biver 

 and Granger, as is shown also on the map of the Green Biver Basin by 

 the survey of the Fortieth Parallel. This area was outside of our dis- 

 trict, and Granger was simply our first supply depot, 



GRANGER TO PORT HALL. 



Taking a month's supply of provisions we started on our second trip 

 June 24. Leaving Granger we followed up Ham's Fork. The second 

 day's march brought us once more within the limits of the district. The 

 valley of Ham's Fork has abundant agricultural land of fine quality, and 

 the neighboring hills are well grassed. The prevailing formation on both 

 sides, from Granger to the first branch coming in from the north, is the 

 Bridger Group. Above the creek just mentioned the river cuts a nar- 

 row canon through beds of Green Biver Tertiary age. 



The road that follows Ham's Fork is obliged to cross and recross the 

 river several times, and as there are no bridges, the route is one that is 

 used only after the spring floods. A trail, however, follows the north 

 side, and this we utilized, following it through the canon which the 

 stream cuts in its way across Oyster Bidge. Just as the stream enters 

 this canon, it turns at right angles to its former course. We forded the 

 stream on the wagon-road just above the bend, and followed up the right 

 bank until we reached the Sublette road, which comes across from Crow
