You can only see 3,4,5,6 & 7 - the other two are at the top and hidden.
They say these pools never dry up, even in the driest of seasons (except for the top two which are very small). The Indians named them the Seven Sacred Pools and used their waters for bathing and healing. It was also a good place to seek food. Animals would come to get a drink and made for easy hunting. The water is a murky green and strained MIGHT be safe to drink. Clear water is usually poisonous. The green water indicates life is supported in the water, clear not supporting life.
