I'm now on Highway 287, a connector between Highway 200 and I-15. I didn't realize until posting this picture that after Choteau, I had switched to Highway 287 and not 89 which kept going straight and I veered west.

Top photo is heading south on Highway 287 toward some mountains near I-15 (in the background are probably the Big Belt Mountains). The bottom photo is a way cool mountain called Elephant Mountain just before crossing the Dearborn River.

More of the area can be seen in my video [ youtube video ] Bynum to Butte
