The description states:
332 – NATURAL HISTORY MUSEUM, BALBOA PARK, SAN DIEGO, CALIFORNIA
Balboa Park has been the scene of two international expositions and is the cultural and recreational center of the city. The great halls of the Natural History Museum house displays of the flora and fauna of the San Diego region.
—The museum has expanded to more than double the original floorspace, although this is not obvious from photos because half of the building was left as a facade for decades after it opened. Its increased size has allowed the museum to host traveling exhibits like the Dead Sea Scrolls.
This postcard was used and is dated 20 July 1955.

C.T. Art-Colortone, Western Publishing and Novelty Co., Los Angeles, Calif.

There is no description on the back of this card. There is handwriting there, and it appears to list the titles of several popular songs of the time, the most obvious being “I Found a Million Dollar Baby”, which was published in 1931 and first performed by Fanny Bryce, then recorded by many others, including Bing Crosby, also in 1931. This indicates the card likely dates from the 1930s.

Golden Canyon, Funeral Mountains, Death Valley, California

Frasher’s Fotos, Pomona, Calif.

There is no description on the back of the card. The Death Valley National Park is not a true valley. Instead, it is a graben, or a block of land that has been lowered by tectonic activity between two other rising blocks. It became famous for it’s borax mines which provided soap and laundry powder to the U.S. consumer in the middle of the 20th century.
The lonely automobile shown in the image indicates the card likely dates from the 1930s.

Joshua Tree, California

The description on the back of the card states:
DESERT LANDSCAPE
Colorful jagged mountains, arid wastelands, and the grotesque desert Joshua tree form a typical scene on the desert, now crossed in comfort on smooth, paved highways which connect one cool green oasis to another.
–The description refers to the US Highways, and later Interstate Highways, which facilitated safe travel across these otherwise uninhabited and inhospitable areas. Even today there are large uninhabited desert regions, many of which are state and national parks.
This card likely dates from the 1950s.

The description states:
DONNER LAKE
Located in California near the Nevada line, the serene beauty of Donner Lake makes it hard to realize that men once suffered here. The Donner party left Springfield, Illinois, in April, 1846, and were hemmed in at the lake by early snows. The sculptured figures of a man, woman, and child memorialize the Donner tragedy.
–The lake is not far from the much larger Lake Tahoe, on the eastern side of the Sierra Nevada.
This postcard likely dates from the 1950s.
