view looking up an old lava flow that historically game down the side of a volcano in Cost Rica. The lava flow was inside an old lava tube, but the roof and lot of the sides have eroded away over many thousands of years and leave rib like jagged spiky structures that curve into the sky. The jungle has started to take over the black lava flow, with new growth in many of the cracks. Wide angle, photo, colour, travel photography. --ar 16:9 --style raw
