Want to see Patagonia, one of the coolest places on Earth from the comfort of your own device. Step right in and lets go on a walkabout...
Introduction
Here is my second ever drone video. It was posted on dtube. The video was taken in the Southern Andes of South America by drone. You are going to see, glacial geology, glacial geomorphology, glacial erosion, glaciers, and some beautiful views. You may also see the occasional propeller (sorry still working on getting those out of the shot). Hopefully one can forgive the learning curve and enjoy it for what it is and enjoy the #music as well.
Geology and Geomorphology
The towers and peaks in the middle are intrusive rocks, hard, resistant rocks, poorly erodible rocks that recently had or some still have ice (glacial) surrounding and covering them. The lakes around the video are filling depressions left over (actually scoured out) from when the main icecap covered this area (one of the largest blocks of ice on earth outside of the Polar Regions - the Southern Patagonian Icecap/Icefield). During the last ice age or Last Glacial Maximum (LGM) ice covered almost everything you see here until around 17,400 years before present (Reference 1 - Garcia et al., 2014). Can you picture almost everything you see in this video covered with ice? Amazing!
The towers in the middle of the video are the famous "Torre del Paine" laccolith, or sheet intrusion (i.e. igneous intrusive), that was injected 12 ± 2 Ma (Ma = Million years - using a Rb/Sr model) and 13 ± 1 Ma (using a K-Ar biotite), respectively into the overlying sedimentary rocks (Reference 2 - Halpern, 1973). Intense episodes of glacial erosion during the Quaternary (last 2.6 Ma) allowed these towers to be formed from the laccolith and preserved this beautiful glacial geomorphology (including aretes, horns (the torres), hanging valleys), made of beautiful hard intrusive rocks (with sometimes a bit of glacial ice still on it) to the present for us to enjoy.
Oh yeah, those towers also make for amazing #climbing or #rockclimbing. If you are strong/brave/crazy enough...
Press play and you are in for a treat... (video works best in Chrome). Enjoy and hope you like the music as well.
Hope this inspires you for your own explorations.
