Huevos del Teide lava balls, Tenerife

by Jana Eichel, Karlsruhe Institute of Technology, Karlsruhe, Germany

The 'Teide eggs' are pieces of lava which detached from the dark lava flow ('lavas negras') in the back of the picture and rolled downhill, forming into these large accretionary lava balls. They can be found at the northern flank of the Teide summit within the lighter-coloured reddish lava of the 'Montaña Blanca'.
