For a hidden geyser, I can set it's priority to !! - yellow alert - and then when I click on it I can see the geyser info with the type listed.
This seems like a minor but really since I know how it works (from the forums) I just can't keep myself from doing it, although I really think that the game would be more interesting if I had to actually dig the thing up to know what it is.
Steps to Reproduce
1. uncover hidden geyser from the fog of unknown 2. set it's priority to yellow alert 3. click on the alert message in the top left corner 4. see the geyser info in the bottom right corner
