Since we are in the area, let's visit Grand Teton National Park and John D. Rockefeller Memorial Parkway. This map is from the Park website.
There is WPA poster aesthetic and then there is Paint by Number aesthetic, and this postcard is over the line, in Paint by Number territory!Giving credit where credit is due:
The back of this card says:"Works Progress Administration (WPA) circa 1939, Artist Unknown. Between 1935 and 1943 the WPA's Federal Art Project printed over two million posters in 35,000 different designs to stir the public's imagination for education, theater, health, safety, and travel. Due to their fragile nature only two thousand posters have survived. The National Park image shown here is also available in the original poster format from many National Park bookstores."

A beautiful valley is dominated by tall mountains on the west - jagged peaks rising almost straight from the valley floor, or so it seems. You have seen pictures of this place. A meadow with a zigzag fence with sharp rocky peaks in the background? A stream in a grassy valley, again with those peaks?

A beautiful large lake with impossibly steep mountains in the background?

Yes, that is the Grand Teton National Park, and Jenny Lake is the name of that lake.
The museum is now called the Jenny Lake Visitor Center. It is open from May 14 to Sept. 22, and offers walks and talks with the rangers.
I have visited here, and pictures capture only a little of the beauty, majesty and just the air and the light of this place.
Thank you to our hostess Beth at The Best Hearts are Crunchy for hosting Postcard Friendship Friday.
