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!

Breaking Gear Fear

Edutainment has been a great way to help people understand their gear, and know the true limitations of it.  Watching HOW gear fails is more important than the force itself, as almost all gear is super good enough.  It's more important to share information on how to stay safe than it is to have a paywall.  We hope our stoke is contagious.
