User reviews

Really great

Love it! Wish I could copy the text descriptions though. Other than that, I highly recommend it to students and professionals. A+++

Old Man

I’ve had this app for a few years or more now. Very impressive. The search feature is Awesome. Search by the actual address is “very helpful “ Well done.

Love the Latest Update

Mancos keeps getting better and better. I especially enjoy the seemless drill down from continent-wide views, all the way to my street and house, with clickable geological overlays.

Add to that, nearest strat columns, and paleo links ... Mancos is by far the best geology app available.

Strongly recommended.

Great Tool

Has helped me locate actual and potential fossil sites. Not for everyone, but it works very well for me.

Broken

Does not show geology overlay at all, just some orange lines. Cannot close the stratigraphic column even though none of it is shown on the map anyway. Stopped working on my iPad Mini and iPad Air so apparently the app is broken.
