On the way home with our new Cessna 120 I saw some spectacular views. This is near Guadalupe Peak at the corner of Texas and New Mexico. I've been past this place before, but it never ceases to amaze me.
Mountain flying presents some serious challenges for pilots and many Texas pilots have never flown in the kinds of conditions that you can find yourself in in mountainous country. If you will be flying into these areas, at a minimum read up and talk to instructors who know more about mountain flying, or better yet, go take a course somewhere where experienced mountain pilots can give you good training.
Here is another mountain nearby.
