What does God love so much about the mountains?

I am eagerly waiting for the Revelation Bible Study's editing process to be complete so that I can release the first session. I am in awe to look back on my life and see how God has prepared me for this calling in my life to study the book of Revelation and teach it. I believe my preparation began as young girl; I would put on an old wool skirt - which I have no idea where it came from, but I liked that it was long - with my mom's old high heels and I would teach for hours on end. I took it so seriously. Little did I know, all those years of teaching in my wool skirt and old high heels would be training to teach what I have learned in Revelation 30 years later. Not only did God prepare me to teach, but He taught me how to study His word with no outside influences, no commentaries or any other book written by man; just me, my Bible, and the Holy Spirit. He did this by putting a question on my heart. I wanted to know what God loved so much about the mountains. Stop and think about it, Abraham, Noah, Moses, and Jesus all had mountain top experiences. What did God love so much about the mountains? God used this simple question and my quest to uncover the answer to teach me how to study using His word alone. It was fun and fascinating, and I learned more of who God is studying the mountains of the Bible then in any other study I have done. One day I can't wait to share this study with you! To God be the glory!!!
