It’s “an avenue of mostly dead Aloidendron ramosissimum,” Foden said. The plant is known as the maiden’s quiver tree in Namaqualand’s Richtersveld National Park.

Each dead tree is a tombstone, marking where the bushy aloe once thrived. Each is a sun-cured skeleton, long having shed the fleshy canopy of olive-green leaves that were reservoirs of water.
