I have done a bit of bike riding these past 2 weekends, taking advantage of the fairly extensive bike path system that Westminster has.
This is south-west of here, near Stanley Lake, about 45 minutes away (on bike)

From a lake in Thornton (I had to go under I-25 to get here, and went over I-25 on the way back)

to looking at cave drawings:

to the intersection of Decatur and Decatur.
