Left from Deaver on State 114 over beet-growing land to GARLAND, 11.7 m. (4,247 alt., 85 pop.), a beet-growers' hamlet at the junction of State 114 with State 14 (see Tour 10A).
North of Deaver, ranches and small irrigated farms spot the alkaline flats.
FRANNIE, 47.4 m. (4,219 alt., 50 pop.), named for a settler's daughter, is a supply point for oil fields near by and a railroad junction, from which a branch runs southwest to Cody. Large trucks rumble along the highway, loaded with oil and oil-well casing.
Left from Frannie on a dirt road to the ELK BASIN OIL FIELD, 15 m.
At 48.7 m. is the junction with a graded road.
Left on this road to the FRANNIE OIL FIELD, 1 m. Derricks and storage tanks rise on the slopes.
At 49.6 m., where drab foothills hide the more distant mountain ranges on either side, US 310 crosses the MONTANA LINE, 74 miles south of Billings, Montana.
Junction with US 287-- Jackson--Junction with US 189--Rock Springs; 214.6 m., US 187.
Oil-surfaced and graveled; closed between Moran and Jackson in winter. Good accommodations at long intervals.
Between northern Jackson Hole and Rock Springs, US 187 passes through strikingly diverse areas. Rugged snow-capped summits and timbered slopes are mirrored in clear lakes. Primitive areas shelter elk and other wild animals. Then the route cuts southeastward, through spectacular canyons, native meadows, and mountain parks, and crosses a desert of salt sage to connect with the Lincoln Highway.
From forest land along the edge of Jackson Lake, US 187 descends into Jackson Hole, a valley shouldered by spired mountain ranges.
