Lake Natron
Located in Tanzania, Lake Natron is a festering pit of alkali soda and salt. The water in this lake has a ph level of 10.5, which is practically the ph level of ammonia, and its caused by alkali salt deposits that release themselves into the lake intermittently, causing anything or anyone that touches the water to become instantly calcified. Birds and amphibians are regularly found fossilized in crystals around the lake because its reflective surface appears just like normal water. However, you should be warned that even one drop of this water is strong enough to burn a hole through your femur in less than one minute.
