When is a 15-acre wildfire more of a concern than a 26-hundred acre one?

When the larger one -- the biggest in Northern Utah, so far this year -- is in the middle of nowhere...while the smaller one is a quarter mile from homes and cabins.

In Box Elder County, the larger fire is threatening only one remote cabin and some livestock.

But in Sanpete County, about 50 homes and cabins were threatened by the 15-acre blaze. 

Both fires are believed to be lightning-caused. though that remains under investigation.
