And again I found a few beautiful steps with mountain crystal in the mountains near Lake Atitlan in a quartz vein that I found by chance where I was hiking. Because when I go hiking, my head always looks down to see what minerals I can find. And especially here at the lake you can find a lot. If you know a little about what to look out for, you can find a lot here. ranging from obsitian to rock crystal, red jasper as well as agate and calcite. because the lake has a long history.
