On August 21, 19 children participated in the classes “With a backpack along the trail”. This time we learned that you must take with you on a hike, how to determine the cardinal directions, how to remember and find your tree. The older guys enthusiastically counted the annual rings and examined the tops of the trees with binoculars. We walked in a beautiful place, saw mushrooms and flowering herbs. Many thanks to the guys for their activity and interest. We thank the Lake Baikal Foundation for assistance in organizing the classes.
