Question 1

What is this (N 34.64914 W 111.75221) karst landform, how did it form, and what is the
elevation difference between the water in this landform and the stream immediately to
the east?
This landform is a sinkhole formed by faulting dropping down the basin. The river to the east is a few
meters lower than the lake in the sinkhole.
This landform is a caldera formed by the collapse of the volcanic basalt lava upon evaluation of the lava.
The current lake surface is the same elevation as the river to the east.
This landform is a blind valley formed by fluvial processes eroding the depressions, and the river to the
east is about 10 meters higher than the lake surface.
Correct!
This landform is a collapse doline formed by the dissolution of rock (limestone) in a cavern. Then, when
the cavern ceiling collapsed this sinkhole formed. The elevation of the river to the east is a few meters
lower than the lake.
This location is Montezuma's Well. It is a fantastic place to explore:

It is also a great picnic spot about half-way between Phoenix and Flagstaff.
