Image 2 shows the relationship of the Meeting Spot (near top of image) and the main state routes (260 and 87), Payson, Whispering Pines as well as another spot of Geologic interest which is a view point for the Great Unconformity.  (More information is found below.)

What is the Great Unconformity you ask?  I'm glad you asked that question.  I have created a short video answering that burning question.  Here is a link to it that is on my YouTube Channel:  https://www.youtube.com/watch?v=bM1R4HyezhM

This is the view of the Great Unconformity.  So, as you are driving along Houston Mesa Road north of Payson, definitely make a short stop to see the Geologic wonder.  Early morning is a fine time of the day to view it... as well as contemplating your existence in the cosmos.
