This is an easy drive-to summit on Forest Service roads. See link below for map of route. It will take you approximately one hour from downtown Plains, Montana to get to the summit. Four wheel drive not needed. The only downside are the large communication towers that will interfere with your transmitting. I found that if you drive to the far side of the loop road and get the towers out of sight, you can get a good signal to and from Missoula and up to Whitefish. Let me know when you plan to activate this easy one and I'll chase you as I live in Plains.

Finally got the round-tuit for my first activation.  First Butte had not yet been actiivated and looked pretty easy so off we went.  It isn't much of a hike.  There is a high clearance forest road that takes you to the summit.  Some internet sites report that the Bromas Creek approach is closed due to a washout on NFR 37.   The Forest Service has built a detour, NFR 3700-805 that is not on the FS map but connects to 3700-825.
