The Rahr Memorial School Forest is located north of the Point Beach State Forest on the shore of Lake Michigan.  The School Forest contains a total of 293.31acres located in the townships of Two Rivers and Two Creeks in Manitowoc County. 

There have been several changes in landforms over time due to glaciations, fluctuations in Lake Michigan’s water levels, and the effects caused by wind blown sand.  Glacial Lake Nippissing covered the area 4,000 years ago.  The present Lake Michigan levels existed about 2,000 years ago. The three soil types, as reported by the Soil Survey of Manitowoc County, include Bridgeman fine sand, dune sand, and peat. 

Many species of trees exist within the School Forest including oak, aspen, maple, white pine, red pine, hemlock, paper birch, yellow birch, jack pine, Norway spruce, white cedar, and green ash.  There is also a variety of herbaceous plants including grasses, sedges, wildflowers, shrubs, invasive plants, and rare specimens.

Wildlife that can be found at the School Forest includes grey fox, red fox, white-tail deer, wild turkey, raccoon, turtle, frog, toad, salamander, fish, hawk, owl, skunk, waterfowl, song birds, coyote, insects, and many more.



There is no date available, but it is known that Native Americans inhabited the area near the site of the School Forest sometime after the retreat of the last glacier which created the unique ridges and swales.  There is a site on the south side of Molash Creek (in Point Beach State Forest) where chips can be found which were remnants of arrowhead making.  The chips are from orange igneous rocks.  Since no igneous rocks are found in this area, the rocks had to be carried in.  There is an old Indian road, which ran from Green Bay to Milwaukee along the lakeshore.

From the early 1800s onward, lumber and forestry products were the major industries.  In 1852, 90% of the exports were lumber and forestry products. Wood was used for posts, shingles and lathes.  The hemlock trees from Two Rivers north to Two Creeks were cut for lumber.  The bark was used in the tanning industry (from which Tannery Road received its name).  Peeling and boiling the hemlock bark produced tannic acid, which was used in the softening of animal hides, as they became leather. The logs were sent to the area sawmills to become lumber.

Firewood was cut to fire the many steamships which frequented the area.  The wood was hauled to Lake Michigan piers for the ships.  The whole School Forest property was eventually logged off.  It is reported that—at any time during this period—people could stand on the shore near the School  Forest property and see at least two steam ships.  The SS Vernon sank off the School Forest property and floated to the southeast.  Many people drowned, were unidentified, and are buried in a mass grave in Two Rivers.  In 1872, shipping logs reflect that there were fewer forestry products and more agricultural products, such as wheat, beef, and hides being shipped.  This indicated that the land had been cleared for farming. The climate was found to be conducive for agriculture as it was level and with decent soil.  The soil absorbed moisture from the lake during the night to enhance growing.

The infamous Peshtigo Fire began on October 8, 1871, and burned into northeastern Wisconsin, including what is now School Forest property. The story has been written up in the Manitowoc Historical Society monoliths.  On the south eighty, there are no really big, old trees.  What are big trees now would have been very young at that time.

Another fire on the property occurred in 1954 between the lake and the lodge area.  Taking two days to put it out, no one knows how it started. Traces can still be seen.  By reaching into the hollowed-out trunks, charcoal can be extracted.

In 1998, a small forest fire burned one acre.  On April 24, 2000, approximately 15-20 acres in the northeast part of the South 80 were burned in a forest fire.  The cause of both of these fires is unknown.

Also there are two trash piles on the property known formerly as the Rebarchek farm.  One is near the pond and the other is southwest of the hemlock forest.  The property was purchased in 1955 so the piles preceded this date.  Glass and heavier metals have been found but, interestingly, no plastics have been found.


The idea of establishing a School Forest came about through a series of events.  In 1950, a group of fifth and sixth graders planted trees at Silver Creek Park in Manitowoc.  At Madison School, excitement for the environment was created by a Conservation Corner started in Mr. Allen Peterson’s class.  Also at Madison, Petrea Rahr was in Mr. Eugene Krejcarek’s class where they listened to the “Ranger Mac” program.  Petrea’s father, Guido Rahr, showed a great interest in helping advance environmental education for the students of Manitowoc.  These events built the connections within the community to begin the process of starting a School Forest.   

In December of 1954, the Rahr Foundation purchased land from David Le Clair for the Manitowoc Public School Districtto use as a location for tree planting.  A second parcel of land was purchased from Joseph and Cyril Gehl.  Both of these pieces of land were officially dedicated as the Rahr Memorial School Forest on May 1, 1955.  The first official trees were planted by Mark Hooper, president of the Board of Education, and Mr. Clarence Alt, treasurer of the Rahr Foundation. 

As the 1955-56 school year began, many teachers started to request visits to the forest.  To accommodate these groups, discussion began to build a classroom building.  The building would also provide an ideal spot for the sixth grade camping program which had started in 1952.  This program was started on a trial basis by Mr. Ed Ehlert, principal, and Mr Joseph Rappel, sixth grade teacher, from McKinley School.  It was expanded to include all elementary schools in 1953.  The camp took place at Camp Shaganappi on Lake Winnebago for sixth years and then at Camp Bird in Crivitz. 

The new building was constructed through the efforts of many community groups, Manitowoc families, companies, public entities, and individuals. MPSD staff and supporters worked hard to raise funds.  Madison school principal, Ivon Greene, McKinley School principal, Ed Ehlert,  and Madison teacher, Eugene Krejcarek were among the advocates of the project.  The first sixth grade camp in the new Lodge started on April 28, 1959.

  • 1959 – The Lodge was completed.  The first overnight event took place in the spring. (Later to be named the Ehlert Lodge.)
