Geologic field work often involves driving along paths that really don't qualify as roads. Here we have a stuck geology van in the Drum Mountains of western Utah, USA. The Drum Mountains have well exposed Cambrian rocks. The Cambrian succession is fossiliferous with trilobites and some soft-bodied fossils.
Notice that I am not helping - I'm just taking this photograph. I paid for it. I was later assigned to change a flat tire on four separate occasions during this particular trip.
