Way out west, where fossils are found, brontosaur signs appear all 'round -- and they belong to Sinclair Oil. The iconic brontosaur logo appears at more than 2,700 Sinclair-branded service stations owned by independent operators in 22 western and midwestern US states. The company also operates two oil refineries, more than 1,000 miles of pipelines, exploration operations, and a trucking fleet. It owns a 60,000-barrels-per-day refinery in Sinclair, near Rawlins, Wyoming, and a 20,000-barrels-per-day unit in Casper, Wyoming. Sinclair Oil is owned and led by R. Earl Holding. Holding also owns the Grand America Hotel, the Little America hotel chain, and two ski resorts (Sun Valley in Idaho and Snowbasin in Utah).
