This has the beginnings of a good page and the peak definitely deserves a post. I hope more pictures will be added.
While there is some ambiguity about exactly where the Warners end, there is a bit of consensus that the range ends at Hwy 140. At least for the purposes of Summitpost the Drake/Light Peak area is being considered a separate range. Discussions can be found here:
If you have any indication that the Drake Peak area is part of the Warners, I would be interested to see it. This is not intended in a contentious fashion. On the contrary, it would further the already ongoing discussion on the issue. I hope this is not overkill, and this is all meant constructively. At the very least, this leaves the door open for another, independent page on the entire Drake Peak area.
During a routine google search I found this link, his first publication is about Drake Peak:
http://geomaps.wr.usgs.gov/pacnw/pwells.html
So I followed that up with a google search of a "rhyolite complex" and found this link;
http://volcano.oregonstate.edu/vwdocs/vwlessons/volcano_types/caldera.htm
So that kind of affirms the collapsed shield volcano theory. I suppose someone could contact Ray Wells from the first link to confirm.
I think the explanation on the Drake Mountain page is not entirely correct. I think the Drake area is uplifted thanks to Abert Rim and the North Warners, but I dont think the mountains are a result of uplift.
Bubba took that picture looking north up the Warner Range with Drake and Light on the horizon, and to me this looks a lot like Gearhart, Yamsay, Newberry, and Mazama which are all shield volcanoes.
I am not really contending the naming of the mountains, I just find it interesting. I have tried to find more information on these mountains several times over the years and I havent found much beyond what I have posted here. Oregon Roadside Geology and In Search of Ancient Oregon both fail to talk about this area beyond Crane Peak. I would love to get my hands on a copy of Oregon Geology, but havent tracked one down yet.
