Gray Treefrog Survey
Tuesday, September 18   6pm   Carpenter’s Bottom
Gray Treefrogs fill late spring/early summer with their melodic trills.  They are also great wildlife ambassadors!  Come learn about treefrogs and the survey work to sample for these masters of camouflage.  Join Josh and Junior Naturalists Alison Longwell and Alex Lawson to take part in checking PVC retreats utilized by treefrogs.
 
Puppet Pals:  Magical Monarchs
Thursday, September 20   6pm   Lowe-Volk Park
Friday, September 21   11am   Lowe-Volk Park
The caterpillar does not know why, but she’s “Gotta Go, Gotta Go, Gotta Go to Mexico!”  Follow the adventures of a Monarch as she goes through her various stages of life, all the while meeting different animals on her journey to Mexico.  Puppet show will include a kids’ activity.  For kids ages 3-7 and their parents.   
 
Animals of Halloween: Snakes
Saturday, September 22   2pm   Lowe-Volk Park
Halloween is a time for “Spooky” or “Scary” animals! The snake has been labeled as one of those misunderstood “monsters”. Join Abby to learn about the folklore that causes snakes to be used during Halloween and how we can combat the myths! We encourage people with phobias to come and learn and experience a live snake to overcome their fears!
 
Viewing the Night Sky
Saturday, September 22   8pm   Lowe-Volk Park
Join members of the Crawford Park Astronomy Club as they share their knowledge and telescope skills with all who are interested in the celestial sights. Targets for the fall months will include:  Saturn, Mars, M-32 (an elliptical galaxy), and NGC-869 (a double cluster).  The universe is an astronomical sight!
 
Pickin’ Pawpaws
Sunday, September 23   1pm   Carpenter’s Bottom
Pawpaws are the largest edible tree fruit native to the United States. Join Josh and Lisa for a walk through Carpenter’s Bottom looking for these custard like fruits. We will even sample our harvest.

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.
