## About Mineral Spring (Lower Klawasi Cone)

A mineral spring in the Valdez-Cordova Census Area, tied by name to the Lower Klawasi Cone. Valdez is the nearest town, and it is not close. The notable thing in the record is the water: a 1973 sample returned dissolved solids of 27,500 milligrams per liter, which is salt water, well beyond anything drinkable. No temperature was recorded. no access is on record, and so is land ownership.

A hike of about four and a half miles from Silver Springs Loop Road gets you there, according to the record, with no trail named. The spring sits at moderate elevation. Average temperatures hover around freezing across the year. Roughly four feet of snow falls in a season and total precipitation is on the dry side.

Treat the chemistry as the headline. Water that salty is a curiosity to look at, and the sample is old enough that conditions may have shifted. Because access and ownership are blank, find out who holds the ground before walking in. Summer is the only practical season given the snow. No campground or fee is listed.
