Last week I took my four grandkids to the Sax-Zim Bog in Toivola, Minnesota, appropriately located on Owl Avenue. (It’s a good place to see northern owls.) The drive from my house was one hour and four minutes. (Thank you, GPS.) The grandkids brought library books and their adventure bags, which are filled with postcards, maps, compasses, binoculars, auto bingo, bird books, and other adventuresome stuff. We weren’t one minute from my house when the three youngest grandkids took up an intense game of auto bingo, searching for cows, horses, ambulances, no parking signs, and billboards. However, by the time we were far enough out of the city to see cows and horses, the bingo game had blown over.

Of course, there is always one grandkid who wants to know: How far? How many more miles? Are we halfway there yet? Have you ever been here before?

We arrived at the bog’s parking lot about eleven o’clock. It was 52 degrees and sunny, with a slight breeze — perfect weather for walking through an old bog. But we were glad we’d worn sweatshirts over our T-shirts.

The Sax-Zim Welcome Center was closed, but we met a volunteer coming out of the building who looked like part of an illustration from a Jan Brett book. He kindly answered my questions about the trails because we wanted to walk on the new Taiga Boardwalk built last autumn.

Shortly after we started down the trail, a loud clattering commenced. I wondered, “What kind of bird is that?” Then I discovered two chattering squirrels chasing each other up and down tree trunks and across fallen logs at breakneck speeds like a pair of NASCAR racers. “Those are fox squirrels,” Michael, 10, said. “My grandma has them at her house.” His other grandparents live in rural central Minnesota. But, according to a post on the Friends of Sax-Zim Bog Facebook page, we most likely saw Red Squirrels. They are highly territorial, and one of them probably invaded the other’s space, which would explain their loud scolding sounds and serious chasing behavior. Whether fox squirrels or red squirrels, they were fun to watch.

As we walked through the bog’s forest, I thought about The Hidden Life of Trees by Peter Wohlleben, a book I recently finished reading. I learned a lot about trees and forests. True forests are diverse and interconnected in an amazing cycle of life and death, filled with competitiveness and cooperation, and home to a large variety of insects, animals, and other plants. Forests grown for harvesting are nothing of the sort.

Walking along the trails of the bog, we saw different species of trees. New trees, only inches tall, grew under the branches of old trees. Unless the old tree dies, most, or perhaps all, of the baby trees we saw won’t make it to adulthood. Some standing trees looked nearly dead, waiting for their turn to fall to the forest floor. Tree trunks that had already fallen lay on the ground in different stages of decay, providing habitat for other creatures.

Steeped in tranquility, the breathless silence of the bog held no traffic or city noise. No planes droned overhead. Occasionally, the peaceful quiet was accompanied by the chirps and calls of birds and squirrels, which like the silence, belonged to the forest.

The Taiga Boardwalk loop is short, but it’s not meant for serious hiking. It’s a trail where visitors take their time, stopping to look for birds and animals who are masters at blending into the forest. When we finished the Taiga trail, we weren’t ready to leave the bog, so we walked a different, smaller loop. We still didn’t wanted to leave, so we walked the Taiga again.

On our second trip around the Taiga trail, Evan, 7, got down on his hands and knees, peered through the slats on the boardwalk, and said, “I see why they built this. There is water down there.” I’d told them the boardwalk was built to help keep people’s feet dry.

We didn’t see any owls, but in addition to the red (or fox) squirrels, we saw chickadees, and Clara,12, spotted a black-back woodpecker.

After we finished walking the trails, my youngest grandson Charlie, 5, gave me a hug. “Do you know why I gave you a hug?” he asked. He didn’t wait for an answer. “I gave you a hug because you brought me to this bog.” I think Charlie felt what I felt: a pervasive peacefulness. As I walked through the bog, I felt a sense of increasing serenity. In The Hidden Life of Trees, the author mentions studies that show people have reduced stress levels after walking through old-growth forests. I have no data to prove that is what happened to me, but I certainly felt calmer than when I’d arrived.

Holding our trail maps, Sax-Zim Bog calendars, and warm memories, we got in the van and buckled up. I was about to start the engine when Clara pointed out her window and said, “There’s a butterfly in the parking lot.”

Having recently finished reading Bicycling with Butterflies by Sara Dykman, I had to get out of the van and have a look. As I was snapping pictures of the butterfly, which wasn’t moving much, a red pickup truck pulled into the lot. The only open space for the truck to park happened to be where the butterfly was resting, and the driver wouldn’t have been able to see it. Squashed butterfly, I thought. I walked toward it, and it fluttered a few feet, but in the wrong direction. Coming from another angle, I walked toward it again, and it flew another few feet, but this time it landed out of harm’s way.

The red truck parked without crushing the butterfly. Perhaps it wouldn’t have needed me to save it. Maybe it wouldn’t have been run over, and it would have flown away from the truck instead of into it. But I’m glad I didn’t leave the butterfly’s destiny to fate.

The grandkids and I left the bog and headed back to the city. As I drove down the county roads, they flipped through their calendars, enjoying pictures of the beautiful wildlife who make their homes, for at least part of the year, at the Sax-Zim Bog.
