There are three cinder cones in a row here. They are known north to south as Miter Crater, Crescent Crater, and Terrace Craters.

They are locally famous because they were the last known volcanic eruptions in Utah; the last eruptions were supposedly 1290 AD ± 150 years.

Unfortunately, they are being mined out relatively quickly.

Terrace is a depression. Based on the book (Lake Bonneville), Crescent is the first feature at the north end, then southward, an unnamed cone, then Miter, then a huge depression (Terrace).

It would be interesting to know if Miter is higher than Crescent (esp. due to mining).

Interesting. Your source is probably the correct one and best one to use. It's been a really long time since I've been out there and the book I used (no internet back then!) isn't very detailed. I went out there a few times in the mid (maybe even early?) 1980's and then again in June 1994. The only reason I remember the June 1994 date is because I drove down there from my Grandparent's house (In Delta) in order to get rocks for our (my wife's and my) first house (which was bought in 1994). The landscaping rocks we decorated our yard came from there.

Anyway, here are scans of the old book I used to use. I always assumed that the names of the craters in were listed north to south, but after looking at the book, it never really says which is which in the text. I just assumed so because of the arrangement of the words and volcanoes on the map:
