We are in Douglas County, Nevada, my question is I have 2 pine trees 15 feet apart among 4 other pine trees that have attracted a change of colors to brown /orange. It does not indicate dryness because they get
plenty of watering.
They cbange occurred within “overnight”.

Your trees look healthy and it appears from the photos that they are just starting to lose older needles, which is a natural process. Depending on the species of pine they will lose inner needles from August through December. Some pines will yellow the needles first and then they will fall slowly throughout the year where others will turn needles rust color and lose them within weeks.
I have attached a couple of articles from other states that discuss this natural process.
