I think someone overreacted. I’ve just perused the bill posted in the first LEGISCAN link (which looks like a draft anyway) and found this definition:

<<“Collect” means to take a sample of material, acquire, gather, photograph or otherwise preserve information in any form from open land which is submitted or intended to be submitted to any agency of the state or federal government;>>

So, as long as you don’t collect data with the intention of submitting it to the government, you’re good to go.

This link looks like the final form of the law:

http://legisweb.state.wy.us/2015/bills/SF0012.pdf

which says:

<<“Resource data” does not include data: […]
(D) Collected incidental to a recreational activity or educational activity done with statutory, contractual or other legal authorization to enter or cross open private land and the data is not used for legal or regulatory proceeding.>>

So I guess you can take photos again while hiking. Who knows, maybe even smuggle a thermometer in your tent.
