Come see what the Tree Summit is all about and how it would fit into your curriculum. Learn how i-Tree and other data systems can be used in the classroom to calculate tree benefits and map school grounds. Teachers do not have to be signed up for the Tree Summit to attend. This is the perfect time to get your questions answered about this new middle school and high school program as well as learn some tree science applications for your classroom. Teachers who are signed up for the Summit are encouraged to attend to learn more about the applications for their classroom. Others are welcome to come and learn more about the importance of trees to school grounds.

A Journey Through Time on Little Mountain:

An integrated approach to Science and Social Studies


Friday, Oct. 17, 9am - 1:30pm


Spend the morning taking a journey back in time to the late 1800s when the wealthy men of Cleveland, such as Wade, Garfield and Rockefeller, and their families spent their summers on a plateau called Little Mountain. This unique environment drew visitors from downtown to experience the cool breezes, shade of magnificent white pines and views of Lake Erie. The hotels, spas and ballrooms are all gone now, but a few remnants and indications of their existence remain.


Be one of the first to experience a new field trip offered jointly by The Holden Arboretum and the Lake County Historical Society. On your trip back in time you will be greeted on the mountain by first person interpreters representing a hotel owner, a wealthy guest and a nurse in one of the spas. These individuals make the past come alive and provide perspective on the reasons people vacationed in this area and perhaps why the hotels eventually closed. You will also learn about the unique natural ecosystem that still exists and how it was formed. See first hand where hotel guests carved their names in sandstone in “Devil’s Kitchen.” This trip will show you first hand how integrating science and history is beneficial and engaging.


Participants will learn about the hotel era history and natural history as well as resources that can be provided by the Lake County Historical Society and The Holden Arboretum. A copy of the booklet A Journey Through Time on Little Mountain, will be provided.  


Participants must be able to walk over rough terrain for three miles both uphill and down. Footing can be muddy, slippery and uneven. Rocks, downed trees and hillsides need to be navigated. Those with compromised walking ability are advised not to participate. Prepare for wet and muddy feet. Bring a sack lunch and something to drink.


Cost: $20
