The grounds contain two additional lots of upland and lowland mature wooded forest that contain wetlands, vernal pools, and an area floodplain.
The BCWG placed an emphasis on maintaining floodplains and riparian zones along Beaver Creek and the creation of private trails to observe the natural beauty and wildlife of the area.
NIRM has periodically made the property available to local academic institutions, including Lake Ridge Academy, and provided tours for the students and faculty.
Most of NIRM's artifacts are based on the collections of Col. Raymond C. Vietzen, the curator of the former, defunct Indian Ridge Museum near Elyria, Ohio.
For over sixty-five years, Vietzen and his wife, Ruth Bliss[3] delved into the prehistory and history of the local area and other locations in the United States.
But although Vietzen repeatedly assured the community, (many of whom had donated artifacts to the museum),[4] that his collection would never be sold, his entire estate was auctioned piece-by-piece after his death.
