As mentioned in an earlier blog post, this is the cabin of the sole survivor of the Indian attack on a white settlement in Iowa, know as the Spirit Lake Massacre of 1857. The woman standing in front of the cabin is a re-enactor, providing interpretation of the event for visitors.

There is no description on the back of the card.
The cabin was extensively modified over the years once the original owner returned and used it as a tourist site. A new door and window were installed on the first floor, and a whole new second floor was added, as seen here.
Once the house was given to the state of Iowa as a historic site, the conservators decided to return it to the original appearance during the time of the massacre. The completed restoration is visible here.
The image likely dates from the 1930s.

This image shows the road which passes the Iowa Training School for Boys, a reform school for what were then termed ‘juvenile delinquents’ located just west of Eldora, Iowa.
There is no description on the back of the card.
Such ‘reform schools’ were established throughout the country during this period, with the growth of social services and the development of therapeutic programs for children who had criminal records.
This image is likely from the 1930s.

This image shows a newly constructed roadway bridge which appears to replace an older dirt and gravel route shown in the foreground.
There is no description on the back of the card.
Such construction was a matter of pride and prestige in the 1930’s due to the constraints of the Great Depression in the United States. Such bridges as this allowed much more convenient, safe and speedy travel in rural areas which were still largely served with gravel roads.
This picture likely dates to the 1930s.

This image shows a gravel road as it crosses a water connection between Upper and Lower Pine Lake in Eldora, Iowa.

The picture is not particularly scenic, but typical of postcard photographs of this era. Often photographers would attempt to document recent developments and construction projects in a park rather than the natural appearance as a way to entice tourists to visit.
This picture likely dates from the 1930s.

This image shows one of the dams that form the lakes making up Pine Lake State Park in Iowa. This is obviously Lower Pine Lake dam, as it has a road passing over it, and Upper Pine Lake dam has only a trail.
There is no description on the back of this card.
The dam no longer has this appearance. Though built in 1922, it was modernized and the design significantly changed in 1991. However, the roadway remains in the same location. This image likely dates from the 1930s.

This image shows the lake nearby the previous posting, Upper Pine Lake, which is a short distance from Eldora, Iowa. It is upstream from Lower Pine Lake and also formed by a dam.
There is no description on the back of this card.
This dam for this lake was constructed in 1934 and modified in 1990. This image likely dates from the 1930s.

This image starts a series of older black and white photos of Pine Lake State Park, located near Eldora, Iowa.
There is no description on the back of this card. This is apparently an image of Lower Pine Lake, with a boater in the middle of the lake and another just behind, near the island. The lake was formed by a dam constructed in 1922.
This image likely dates from the 1930s.
