According to the Swiss Valley site (the current name of this area), Little Switzerland opened in 1960. It was purchased by the current owners in 1968 and renamed Swiss Valley. It has been greatly expanded and improved since then, particularly in 1978-9 when they re-contoured, raised and lengthened the hill.
This is now Swiss Valley.

Amazing that Joe Montana skied there while at Notre Dame!
Note: It would have already been Swiss Valley by the time Joe skied there.
Bob: read my story about Joe Montana under the Swiss Valley (current areas)
Everybody should read Tater’s story under the Swiss Valley page. Amazing that Tater skied with Joe Montana twice! It’s a MUST read!
BtwLittle Switzerland/ Swiss Valley is in Jones Mich, not Three Rivers.
