A colleague of mine wondered if springhouses from the Midwest might be 
of interest?  He has listed them below:

In Bourbon Co., Kansas, site 14BO3498 has a springhouse (there are many 
photos and a site plan map with the form).  There is one other Kansas 
springhouse site that I thought I had reported but (much to my surprise) 
it has not.  It is located perhaps a block NE of site 14BO434.  I will 
try to get it reported one of these days when I can find some time.

In Missouri, I have reported three sites with springhouses.  They have 
site numbers and are described in the gray literature (in two CRM 
reports that can be obtained from MoDNR) as follows:
