An intersting lake in Nevada in EarthCaches Posted July 12, 2010 Sounds great! I've always been curious myself what makes some lakes "salty" and other ones not. You might also be able to talk about how the lake was formed and what's causing it to evaporate. For an educational task maybe you could even have people taste the water and describe how salty it is?? Let us know if and when you get it published. I'd love to read about it!
