Volcano ground anchors for highlining are stronger than you think! Volcano National Park, Hawaii

Jeremiah Morgan (@jeramayan) has been studying ground anchors for some time so he can safely rig some difficult to rig slacklines in Hawaii. We spent an afternoon testing ground anchors in horrible volcanic rock. 15:1 pullies and 5 friends and a dynamometer can be more fun than you think. Don't try this at home, unless you live in Hawaii next to a Volcano! Thank you for your help Hai Thai (@knivesthai), Joe Britt @notahighliner), and Nick Naed for science!
