I know that area well, I even lived on an acreage about 20 miles due east of it for a year, but that was many years ago. The area just NW of there is called the gap and 2 of my good friends have cabins on the way there.
Todd creek area is usually windy as hell so most people spend their time a few miles further west where the land and the terrain provides a more hospitable and scenic experience.
I did try to find the hillspring property on a previous occassion I was down south but didnt manage to find it. If i get down to waterton soon I will take the hillspring road and see if I see anything new.
