The skeleton of a cactus

Seeing a cactus skeleton is a good way to understand how much water they store.

The large black things are hare droppings. The tiny black dots that cover everything is called cryptobiotic soil: “cyanobacteria that cement the soil together. It provides nutrients for plants and seeds, and increases the soil topography which allows greater moisture absorption. This crust is only a few millimeters thick and is easily destroyed when walked on. Recovery can take between 7 and 250 years. Please donʼt walk on it.”
