People walk aroud stone mushrooms rock formations near the town of Beli Plast some 160 kms (100 miles) south-east of the Bulgarian capital Sofia, Saturday, May, 23, 2015. The stone mushrooms are rock formations is a veri popular tourist atraction located at the road, connecting Kardzhali with Haskovo. The protected site has a total area of 3 hectares. It was declared a natural landmark by a Government order in May, 13, 1974. The rock formations have the shape of natural mushrooms - their stalks are pink, and the caps are green. The height of the mushroom stalks and the width of the caps are up to 2.5 meters. They are made of rhyolite volcanic tuffs, which are the result of intensive underwater volcanic activity, dating back to the Paleocene. After the sea withdrawal and the consistent seabed rising, the influence of the erosion became visible. The lower, pink layer proved to be softer and more amenable to the effects of sun, wind and rain. The upper, green layer contains solid minerals, mainly volcanic glass and it is therefore more difficult to weather. So a wonderful combination of unique shapes and colors has formed over the millennia. Photo by: Petar Petrov/Impact Press Group/NurPhoto
