ice on the 911-pond
this pond is slightly salty.
what causes the colors?
As i was reading a geological survey book of 1957, because i am trying to research geological activity in the Sifton Range in them early days. I did come upon something else i once researched without any luck.
As with the Sifton Range, not everything is on google in this day and age, and not everything is known by geologists alive today.... doh.
I am just going to copy here what i found, because when i need this information and will want to do something with it, ( mainly i want to know if the salt is fit for human consumption),
I just have to google it!
"It proved on examination to be composed for the most part of a mixture of hydrated sulphates of sodium and calcium, and a small quantity of magnesium sulphate, with some insoluble argillaceous and organic matters. It is slightly ferruginous, and contains also a very small quantity of Phosphates and chlorides."
and the article goes on, it was tested for potash, but only had slight amounts of it, 0.2 or 0.3 percent K2O
