Old Hamilton Montana Postcards

This postcard says "Timothy and Clover, 5 1.2 Tons per Acre, near Hamilton, Montana"
It was mailed with a one cent stamp around 1911 !!!!

Here's an old Hamilton, Montana scene that looks like it's from the 30's. No clue from the postcard as to the actual date. I'm going to go out and try to find this same spot and take a new picture to compare.

This cool postcard has a place on the back for a one-cent stamp, which means it would be from the early 1900's.
It says, "Fruit Ranch, Bitter Root Valley, Montana."
The Bitterroot valley was once home to a giant apple boom when a giant irrigation system was put in the valley in the hopes of turning the valley into an orchard mecca.

Here's a great Main Street scene. Postcard is Chrome Era, which means it is 1939 to present. It looks very 1960's to me.
Suggestions anyone?

Here's the same scene, but this is 1977.

Here's a cool aerial view of Hamilton, Montana. 2003

Here is an old Hamilton Mill postcard from 1913
