Mountain range pencil drawing

A few months ago I was doing some work online and in addition to my monetary payment I was given this picture and told that I could do whatever I wanted with it. I made it my desktop for awhile and then just sort of forgot about it. I saw it on my computer yesterday and figured you guys might like to see it. I don't know who drew it because I was never given the artist's name. It wasn't me. I was, however, told that I could do whatever I wanted with it. I find it very peaceful as it reminds me of walking through the Colorado mountains with my mother one time when I was younger. I hope all you enjoy it too.
