Late to the party, but finally sitting down to share my experience:
I and a few others gathered at a local park a few days before Solstice, hiked up to a little clearing, watched the sunrise, then spent time in reflection hiking out and found the stones that spoke to us on our way back to the creek. There we placed our stones together in the center of a circle of the symbols we drew in the dirt by the creek side, and visualized the symbols imbuing into the stones and the sphere encapsulating them. As we placed the stones in the creek we focused on protection for the watershed of that particular creek (Rock Creek) as it is an urban watershed and particularly vulnerable.
This park Iāve lead a Solstice hike at for at least three years now and weāve gathered in this same place each time, so it is somewhere weāll be back to in future winters and itās nice to have added this element of protection to the creek. (Just north of this spot is where we planned to do the summer solstice ritual but I got sick and unable to lead, so folks still gathered there but I did the ceremony on a tree in my property a few miles away.)
And the weather was not too bad this year, so we were able to stay for fellowship, fire, tea, and orange cake after!
