One of my first stops on my Journey through West Texas was at "Monahans Sandhills":http://www.tpwd.state.tx.us/spdest/findadest/parks/monahans_sandhills/ State Park in Monahans, TX.
When I got there it was almost 100 degrees outside with the sun beating straight down on me. The park ranger mentioned that the dunes were 40-60 feet high "right now". That last part — the "right now" — confused me but I didn't ask any questions. Once I was out on the dunes it made perfect sense.
