Perfect App!

I am so glad my mom and I downloaded this on the way up to Mount Lemmon! It was perfectly timed and really had a nice overview of the ecosystems and environmental anomalies of the southern arizona climate! We are both well educated adults and still found it very entertaining as it walks you through the area’s geology, forestry, animal life, and conservation efforts. Is wonderful for all ages and made our drive up Mount Lemmon all the more enjoyable. There is nice background music and amazing recommendations as to where you should stop and look around. Thank you to the creators of this app!

Educational and entertaining tour to Mt. Lemmon

We recently discovered another app used for National and state parks. Searched for one in the Tucson area and this one popped up. It did not disappoint! My husband is a retired Forester-the science is presented for the lay person to enjoy in an entertaining way. He learned as much as I did. It includes historic details including how Mt. Lemmon got its name. We started it at the recommended location and it perfectly matched our ascent up the mountain.
