Monday 3:44 p.m. GMT marks the Autumnal Equinox, the official beginning of fall. Summer’s end. We know it’s here because the sun shines lower in the southern sky. We wait for Indian summer to balance the chilly night air.

It means the sun’s rays beat directly on the equator and there’s as much daylight as darkness.

Seasonal changes come with their own traditions. The next-door neighbor celebrates the Spring Solstice with a garden get-together. A group of fly-fishers gathers on the Crowsnest River each year at the Winter Solstice. Harvest rituals come attached to the Autumnal Equinox.

According to Celtic lore, autumn’s beginning, called Mabon, signals a time to pay our respects to the impending dark and give thanks to the waning sunlight. The equinox honors The Green Man, the God of the Forest, by offering libations to trees, ciders, wines and herbs. Among autumn activities are gathering seed pods, walking in the woods, scattering offerings in harvested fields and adorning burial sites with leaves, acorns, and pine cones to honor those who have passed.

It’s also a time of balance, when we enjoy the fruits of our personal harvests, whether it’s gardening, working, raising families, or just coping with everyday life.

For some, like a core group of Henderson Lake golfers, autumn signals a move from the links to the rinks at The Lethbridge Curling Club. For others, it’s a time to change gear – in storage go the fishing pole, sailboard and garden shears, out come the rifle and rake. Hardcore cyclists, runners and hikers simply dress differently when the seasons change.

Clearly, the seasons relate to how we approach the outdoors. Something compels us to spend time outside. Open Air Magazine released a survey this month of 1,027 adults who were asked what they most look forward to outdoors. Exercise topped the list, followed by inspiration, solitude, forgetting about work and companionship.

For me it can be all those things. When I’m fishing on the river, it doesn’t matter if I catch a rainbow – it’s part of the pot of gold, the total package that leaves me in awe of what we have in Southern Alberta. Expect regular reflections on the wonders of the Prairies, the Porcupines, the unique ecosystems of Waterton and the Castle-Crown and upper Oldman drainages, the infinite natural phenomena they hold and the ways we enjoy them.

This weekend, for example, the TD Friends of The Environment Great Canadian Shoreline Clean-up will focus on the Crowsnest River today and Oldman River in Lethbridge Sunday. The Crowsnest clean-up from 10 a.m. to 12:30 p.m. is organized by the Crowsnest Conservation Society. Meet at Sobey’s parking lot in Blairmore. The local effort by Helen Schuler Coulee Centre and Oldman Watershed Council staff starts at 2 p.m. in the Nature Centre parking lot.

Beyond that, watch for discussion of issues in our corner of the world.

To borrow from Celtic lore: may your Mabon be memorable, and your hearts and spirits be filled to overflowing.
