October 14: Fall chapter meeting
The fall chapter meeting will be held at 11:15 am at the Idaho Pizza Company restaurant at Overland and Orchard in Boise. The guest speaker will be John Hiler, Mountain Home area historian.

September 30: Lander Road outing
We will follow the Lander Road on Forest Service and other roads from the Wyoming border to the Fort Hall Indian Reservation. This is a trek that the chapter might not have done before. It will likely require spending Friday night in Idaho Falls, Pocatello, Soda Springs, or Star Valley, Wyoming, in order to start early in the morning (about 9:00 am). The details and meeting location have not been finalized at this time.

September 25: BSU OSHER Class
Jerry Eichhorst will be teaching a class on the Oregon Trail in Idaho for the BSU OSHER program. If you are a member of OSHER you may have seen this course in their catalog. Contact BSU OSHER for more information. These classes usually sell out within a few days.

August 27: Byway Video outing
The OCTA video master, Richard Hunt, and Jerry Eichhorst will be filming a video of the Main Oregon Trail Back Country Byway. Other members are welcome to follow along if you want to see the entire byway or observe the video creation process.

August 26: Ground penetrating radar outing
A month ago, two cadaver dogs showed strong positive indications of human burials on a small knoll beside the location of a suspected massacre of a wagon train. GPR will be used to scan the top of the knoll to determine if something is indeed buried there.

2023 Convention: Gehring, NE

May 18-20: City of Rocks activities and spring chapter meeting
The annual spring outings with City of Rocks are tentatively scheduled for Thursday and Friday, May 18 and 19, with the spring chapter meeting on Saturday, May 20. Additional details will be available soon. We will be trying to get a reduced rate at the Fairfield Inn in Burley.

April 15: Annual spring byway tour with potluck lunch at Springbriar Winery
We will meet at 8:45am between the McDonalds and the Albertsons at Federal Way and Gowen Road. Then we'll caravan from east of Mountain Home to Boise along the Oregon Trail. Lunch at Sweetbrair Winery - $5 per person for burgers and brats. For the potluck, bring a side dish and/or dessert to share. Also bring your own water and drinks, a camera, warm clothing, etc. To RSVP, please sign up with Jerry at Boise Community Education courses, or This email address is being protected from spambots.
