iceshanty they were claiming to give the ice thickness on lakes in montana, no info available Internet

I was told to go to this website to find out how thick the ice was on any lake in montana, but after two days and 5 hours of exploring every link they had on line I was told that I could not register because I answered some stupid question wrong about what is a 3 letter word for an ice fishing lure and what was the 4th company in a list of companys trying to sell their products through ice shanty. they were a waste of time and I got no service or info from them so why should they even have a web site and waste every sincere fisherman trying to look up some info for safety reasons on false promises??
