Love taco register crumbs

Im having alot of fun with this so far!!!

If I wanted info from Wikipedia I would look it up on Wikipedia. Disappointed is an understatement but perhaps someone else can use/appreciate it. Not for me.

Sourced from wiki I have a thing called internet that does the same thing as this app and uses less storage memory.

A really helpful, useful app, and a great way to learn more about geology!

Its impressive but the pictures are too small to view.

Loving the app

Describes different rocks & their properties

Rating request popped up too early. Haven't used it enough to give valid review. Not going to replace any of the classic texts any time soon, but not bad for free app. A work in progress.
