The image is a photograph of a rocky cliff with a sign that reads "Sprunga Upnast - A Fissure Opens Up". The sign is located on the side of a cliff and is located in a natural area with large rocks and boulders. The sign has a blue background with white text and images.

On the left side of the sign, there is an image of a construction site with a yellow excavator digging a hole in the rock. The excavator is digging into the ground and appears to be in the process of removing the rock from the cliff. On the right side, there are three smaller images of the site, each showing a different scene. The first image shows a person working on the site with the excavator, the second image shows the site being excavated, and the third image shows an excavation site with rocks and debris scattered around. The text on the sign provides information about the site and its purpose.
