Wednesday Rocks: #4

The petrified forest in Namibia's Erongo Region is the result of glacial outwash at the end of a Carboniferous-Permian, Gondwana wide glaciation. The trees are Dadoxylon Arber, an extinct conifer and reach lengths of about 45m (Wikipedia). They are preserved in a palaeo-river channel and recent erosion has uncovered many of the fossilised conifers (Wikipedia). This is evident in the multitude of handwritten 'Petrified Forest' signs along the road from Twyfelfontein to Khorixas. The official park employs people from the area as guides who explain a bit about the geology and botany as you wonder through the silicified trees. The photos below are from the official forest park.
