- Consider active volcanoes like Eyjafjallajökull in Iceland, Mauna Loa in Hawaii and Mount Vesuvius in Italy or dormant/extinct ones like Mount Kilimanjaro in Tanzania and One Tree Hill in New Zealand.
- Whether they are active or not, it can be awe inspiring to see these geological phenomena.
- The lava coming from the volcano can work as the fire in our Elements and Pyromaniac themes and the rock that forms as a result could be incorporated into our Rock, Paper, Scissors theme.
