Lava Butte is quite similar to Pilot Butte in terms of size and form, but with a distinct summit crater, and definitely younger, based on what I see in weathering and colonization by plants. Also, the Lava Butte eruption ended with a basalt flow that extends 2.5 miles to the Deschutes River. I remarked on Thursday that I would guess Pilot Butte is probably Holocene, but according to the Wikipedia Link, Lava Butte is dated at ~7000 years. Given how fresh it looks, I'll step back from my comment on Pilot Butte's age; it's likely Pleistocene. Also like Pilot Butte, there's a paved road to the summit parking area, though access is limited and first-come, first-served. In the cropped, processed image below, the road to the summit is clearly visible, climbing from the middle of the cone to the upper right.
