W7O/CE-088
The drive from Glass Butte to Little Glass Butte looks straight forward on a map. It is anything but. 4wd is required and high clearance is recommended. If you do not have these, park at 43.53358, -119.97777 and hike up. Additionally, the rocks on the rough road are obsidian and can puncture tires. Thankfully this did not happen to me, but I was surprised. The road up from the parking coordinates is steep and I nearly stalled getting up it. Pumping the clutch kept me moving. Once up top it is a matter of navigating around ruts and obsidian rocks. I was about at my vehicle's limit.
