Quick Answer
Short answer: To secure a tarp in rocky ground, use rocks, trees, and cordage to create a stable anchor system, and consider using a tarp-specific attachment system or a trekking pole for extra support.
Securing the Tarp
When setting up a tarp shelter on rocky ground, the first step is to identify potential anchor points. Look for large rocks, trees with sturdy branches, or boulders with naturally occurring anchors like crevices or cracks. Use cordage like paracord or nylon rope to secure the tarp to these anchors, aiming for a distance of 6-8 feet between each anchor point to distribute the weight evenly.
Weighting the Tarp
To prevent the tarp from flapping in the wind, use rocks or sandbags to weigh down the edges. Place the weights about 2-3 feet off the ground and 1-2 feet away from the anchor points. This will help to keep the tarp taut and stable while also protecting it from wind-driven debris. For extra stability, consider using a tarp-specific attachment system that allows you to attach the tarp to a tree or a rock without damaging the fabric.
Additional Support
If the rocky ground makes it difficult to find suitable anchor points, consider using a trekking pole or a long stick to provide additional support. Drive the pole into the ground near the anchor points, then tie the tarp to the pole using cordage. This will help to distribute the weight of the tarp more evenly and prevent it from sagging or flapping in the wind.
