Phoenix Mountains by Lionheart Creations is a addon package for Flight Simulator X (FSX) and Prepar3D (P3D) and features photo realistic textures of the mountains of Phoenix Arizona in the USA.  This is only mountains and not the entire city.  They include their night textures and only feature the mountains in and surrounding Phoenix and not farther out in the countrysides.  Only the City mountains.  This serves as a unique, very nice 'landmarks' package and makes Phoenix with the 'stock environment of Phoenix look far more realistic then it was before.

You must manually activate the scenery in your flight simulator.  FSX has a bug where adding on scenery requires you to do a funny little double selection in the 'LHC_Phoenix_Mountains/scenery' folder where you select that, then modify the Directory label back to 'LHC_Phoenix_Mountains' and click OK to activate it.  The scenery installer works to install the scenery into your simulator, but then you must 'activate' it in the sim in the 'Addon Scenery' center.  And thats it.

Hope you enjoy it.  What a world of difference this makes.  The White Tanks, Superstitions, Squaw Peak and Camelback Mountain, Gila Bend and South Mountain ranges look brilliant now with this addon pack.
