This image shows the bluff of a large hill from the Lake of the Clouds, a lake in Ontonagon County, Michigan, in the Upper Peninsula.
The description “far end of the lake” implies the bluff is downstream from the inflow to the lake, which is fed and drained by the Carp River.
This card likely dates from the 1940s.

This image displays the unique transportation method used in the mid-20th century for tourists to visit the Tahquamenon River area. The name is from a popular cartoon of the early 20th century called Toonerville Folks. The name has been used by other public transport methods elsewhere in the United States.

The casual seating arrangements, particularly evident at the back of the trolley where tourists are seated on the trailing edge of the car, are indicative of a trolley that moves very slowly across flat land. Another image, posted on this site some months ago, shows later development of the cars used for passengers and the type of motive power for the trolley.
This card is dated 1941 on the front.

This image is an older, but near duplicate of the image listed some months back. It shows the Upper Tahquamenon falls from a slight elevation and from the opposite bank from the previous posting.

The postcard is clearly dated 1948 on its face.

This placid photo features a small section of the Tahquamenon River near the village of Soo Junction, Michigan. It is not an incorporated town, only a populated area named by the locals as a convenience. This is in the upper peninsula of Michigan, in Luce County.

The Tahquamenon River flows through the center of the upper peninsula of Michigan on it’s way to the mouth at Lake Superior.
This card is dated on the front 1948.

This is again an image similar to one previously posted some months ago. It is obviously the same location from the prominent ‘bulge’ of water near the center of the falls present in both pictures.

The people shown in the photo at lower left are wearing clothing that indicates this image is from the 1940s. Close examination of the picture reveals another person on a ledge just behind the falls.

This is another image of a boat featured some months back. This image is closer in and in black and white, but otherwise the images are remarkably similar in that the boat does not appear to have been replaced, and the tourist still occupy the usual locations.

The boat itself is also called the Tahquamenon, as indicated by the name sign visible in the picture.
The brown marking in the upper right is damage from a decomposed rubber band. This image is hard to date, but is likely from the 1940s.
There is no description on the back.

This is the somewhat overbuilt signpost for Michigan highway M-115, which has one end in central lower Michigan and continues to the northwest where it ends at this sign.
The highway was originally earthen pavement when first constructed in 1929, but by the mid-30s the state was repaving the existing sections with asphalt and extending the highway with gravel as well.
There is no description on the back of this card. The auto in the picture, along with the initial construction date, indicate that this photo is from the 1930s.
