Happy 4th of July from the Michigan Geological Survey!

Field work in this heat is no joke!
While some MGS field work had to be suspended this week to mitigate safety risks, other work (like this geophysical survey in the Upper Peninsula) went ahead, just without straying too far from the truck.
Mineral Monday at MGS!
Is that a space rock? Not this piece from Luning, Nevada, but we have found this mineral on Mars!
Jarosite forms as a secondary mineral in oxidizing, highly acidic environments like mine drainage sites. Its widespread presence on Mars is a key indicator of a past presence of water.
Jarosite has been nicknamed the “golden sponge” because of its ability to naturally trap toxic heavy metals in mining waste.
