Some of the Green sand
DTP-4 is the 4th territory planet Deron discovered. It is famous for 2 reasons: For it's green sand beaches and it's strange Tri-Volcano. The green sand is made of small pieces of olivine and jade. However, the tri-cratered, cinder cone volcano that rebuilds itself is even stranger. It is the only volcano on the planet. It erupts once every 74 marins. Every 148 marins, the volcano destroys it's own cone with a massive eruption, but with that eruption, more ash falls and builds a new cone.
The 3 cones building. 1 cone is almost finished, another is starting, and the third isn't visible.
