Wild Wednesdays
Wed. April 18 10am & 2pm Lowe-Volk Park
Come to the Nature Center and enjoy an hour of nature exploration!  Proram topics will vary and may include a story, short hike, craft, or a visit from an animal.  For Preschoolers and their parents.  Come dressed for the weather.  Morning and afternoon programs will be similar, just choose the time that best fits your schedule.
 
Chicks Dig Birds
Thursday, April 19 6pm Lowe-Volk Park
“Cheep! Cheep!” Spring is a time for birds to build nests and raise their chicks. Some chicks are born featherless and helpless, while others may be born with feathers and ready to run or swim looking for their own food. Joy Etter-Link will have fun chick activities and special visitors for this program about bird chicks. Fun for the whole family.

Earth Day Fair
Saturday, April 21 11am-2pm Lowe-Volk Park
The Crawford Park District is partnering with many local organizations to host our annual Earth Day Fair. The focus of this event is not only to get people thinking about the 3 R’s — Reduce, Reuse, Recycle — but also about sustainability, creating backyard habitat, and much more! There will be many “green” table displays and activities. The following displays and activities planned include: Recycle Trailer and display from Crawford County Solid Waste District, interactive “living stream” display from ODNR Scenic Rivers Program, Recycled Projects from Lisa Smith’s 4th Grade class (Colonel Crawford), Composting Demo from the Soil and Water Cons. Dist., Native Plant Sale, Recycled Nature Craft, Natural Pesticides display, “mud play”, and displays from local businesses that demonstrate the focal points of this event. Come and celebrate Earth Day with us!
 
Our Exceptional Earth
Monday, April 23 6pm Lowe-Volk Park
We live on a truly extraordinary planet, and what better time to learn about it than the day after Earth Day! The earth's systems all work together to create the ideal climate, atmosphere, and ecosystem for all forms of life. Join Mandi Fruth to learn some of these astounding facts and secrets about our unique and balanced planet. We will read a fun book, make a
craft to hang in your window and take a hike to enjoy some of the benefits our Earth provides. For children aged 3-10.

Mastodon Mystery:
Crawford County’s Ice Age

Picture



  
The extinction of over 30 species of mega-fauna occurred over 10,000 years ago.  Lions, cheetahs, camels, sloths, and mammoths are just some of those that vanished from the Earth during the Pleistocene Epoch.  (See page 10 for more information regarding Ohio’s geologic past.)  Unfortunately, confirmation of only one extinct mammal has come to light in Crawford County:  Mastodons.  The following is an overview of the most recent Mastodon finds.
     In 1971, three brothers were playing in the Brokensword Creek, 1 mile northwest of Sulphur Springs, Ohio.  (Isn’t that what kids are supposed to do?)  They found what turned out to be two molars from a Mastodon.  The molars were sent to OSU for examination.  A professor then led a 9-member team to  possibly recover more remains.  A tusk and other bones were found, including the atlas vertebra (C1).  The tusk unfortunately fell apart.  Those pieces were divvied up and given to various individuals and institutions.
     In 1973, a father and his two sons excavated the same site and discovered the other tusk, another tooth, part of a clavicle, and the skull.  The skull was in such poor condition that the only parts saved were the bones of the ears and a part of the jaw that formerly held a tusk.  These items are currently in a private collection.
    
     In the fall of 2009, the Crawford Park District attempted to determine the exact site of the Sulphur Springs Mastodon, in hopes that more bones could be discovered.  (Oddly enough, there was no record as to the exact location of the find.)  Over the course of three digs, it was determined that, based on the shifting of the subsoil, the original site had been located.  Unfortunately, no other bones were found.  The assumption was that the rest of the body had washed down stream.
     In the fall of 2017, while walking in the Brokensword Creek, Chris Rothhaar kicked up a curious object from the creek bed.  It turned out to be a Mastodon rib!  While only a few hundred yards downstream from the original Mastodon find, it is presumed to be from the same animal; however, this is not definitive.  Where the rest of the skeleton is for this animal remains to be seen. 
     Other Mastodon remains have been found in Crawford County.  The most complete skeleton, referred to as the Hahn Mastodon, was discovered in 1838 near the tracks on Hopley Avenue in Bucyrus.  Documents claim it to have been a complete skeleton.  Unfortunately, it is presumed to have been consumed by fire in a Philadelphia museum.  Two other references from the Ohio History Connection cite a Mastodon being found in Chatfield (1880, disposition unknown), and a Mastodon molar in Bucyrus Township (date unknown, now at OSU’s Orton Hall).
     Currently, the Crawford Park District has the atlas, a molar, and a rib, all presumed to be from the Sulphur Springs Mastodon, on temporary display at the Nature Center.  A long-term exhibit is being developed for the three pieces.  Stop in to see a piece of Crawford County’s history.    
     The CPD would like to thank the following for assisting in the documentation of Crawford County’s Ice Age History:  Dale Stansbury, Dale Gnidovec of OSU’s Orton Hall, The Ohio History Connection, Tom Kibler, Evelyn Kibler, Chris Rothhaar, and the Medici Family.

A Visit Through Ohio’s Geology

Picture
Studying Ohio’s geologic history gives insight into how our landscape has changed.  During the Pre-Cambrian, our igneous and metamorphic “basement rocks” formed.  These are known only from deep drillings.  After this period, evidence of the last 570 million years can be seen somewhere near the surface in Ohio.  Seas came and went throughout the Cambrian, Ordivician, Silurian, and Devonian Periods, providing deposition for many sedimentary rocks; the Carboniferous Period was punctuated by an influx in land plants and swamps that created the base for the great coal beds; sedimentary bedrocks of shale, limestone, and coal developed during the Permian Period; and a great void of geologic time (245 million years’ worth) is lost, with natural forces erasing any evidence of the “Age of Dinosaurs” and the “Rise of Mammals”.  
     Most recently, the Quarternary Period has left the most obvious mark on our landscape.  During the latter part of this period, the Pleistocene Epoch – better known as the Ice Age – gripped Ohio.  Glaciers scraped bedrock and deposited clays, sand, gravel, and rock that we see today.  Ohio had at least three major glaciation events, the last being the Wisconsinan.  (If there were more, proceeding glaciers erased that evidence.)  As this last glacial ice sheet receded, it left behind a landscape similar to a tundra that gave way to a spruce bog habitat.  Within these habitats, the last of the now-extinct prehistoric mammals eked out their final days.
