Update: The Llano Earth Art Fest will be held March 9-12, 2018 with rock stacking competitions held on both Saturday and Sunday. Categories have been expanded and include team events as well as individual. Amateurs are encouraged to participate in addition to the professionals. There's no charge for watching the competitions, which are simply amazing.
I watched Michael Grab, an artist from Boulder, Colorado, demonstrate his rock stacking technique at the Llano Earth Art Fest. If you missed this unique Texas event earlier in March, plan to attend next year.
Don't know much about rock stacking?
Find out about this ancient activity--including the World Rock Stacking Championship--that is becoming one of man's newest diversions in my article for Texas Highways magazine.
