Arco is a small town of just over 1000 people. It is the county seat of Butte County but I did not see the courthouse to take any photos. Frankly, I was trying to hurry and get to the Craters of the Moon National Monument. I was behind schedule due to road construction. I did see a few nice buildings in the Historic District that were of historic and/or architectural interest. I liked this one best. I'll see the courthouse next trip.
