When rain comes to desert everything seems to be in a rush. The dry dust on top of the ground seems to absorb the first few drops as fast as it comes, and the plants suck the water out as soon as they can. Once the top saturates the hard baked desert floor sends the rest off as runoff, and it’s not unusual to see desert animals leaving whatever shelter they first took to drink in the short-lived streams.
On the mountain, however, things are not quite as rushed. The angles and cracks in the rock provide sheltered places for water to flow and seep into, perhaps to re-emerge many feet away as a slow trickle, and the eroded depressions create a landscape of micro-lakes waiting to be explored.
