Beyond the Dunes

Skyline Beyond the Dunes It's not uncommon to see the Chicago skyline across Lake Michigan from the Indiana Dunes National Lakeshore, but it seems each time I see it, it's different. Either more or less of the buildings are visible, a superior mirage makes the skyline appear upside-down, or the foreground frames the skyline differently. Every few steps along the paths and trails, the view changes in all directions, and it's interesting to see how things change around the constants of the lake and the skyline. Dune Valley Each turn of the trail brings a fresh look at the dunes. The rolling grasses, conifer forests, oak savanna, and beach all combine with each other like no other place I've visited. In fact, the dunes along Lake Michigan are some of the best places to see dune progression - the change in landscape from beach to old wood forest. As the leaves fill out the trees, the views will once again change- and in some places disappear all together.

Meandering Trail

Meandering Trail An evening hike through the dunes along Lake Michigan - an unusual time for us, as we generally hike in the mornings. We followed the narrow, meandering trail from the beach, through the wooded dunes, along the ridge, and finally through the grassy plains, It's interesting to watch this area come back to life after the winter, the brown grasses shining in the sunlight, will soon green up, as will the trees dotting the dunes.

The Ridge Path This place never seems to get old, and always offers us something different no matter how many times we visit. Behind us are the vast waters of Lake Michigan, offering plenty more interesting views.

Low Sun Behind the Dunes

Low Sun Behind the Dunes

Following our three mile hike to the dune, we climbed up to view the expanse of woods to the south, and Lake Michigan to the north. This particular dune stands between dense woods and the beach, generally covered in marram grass, a large blowout developed over many years, creating the bare area in the center.

A recent controlled burn of the area removed much of the dry grass, revealing the sand below, and dozens of old bottles, cans, and other items left over from the old homes that once stood on the site. We explored the dune ridge, careful as always not to trample any vegetation before making our way down to the beach, and our three mile hike back to the car.

Looking off on the horizon in the center of the image, they skyline of Chicago can be seen, some 40 miles across the lake. This was an unusually clear day - at least the atmosphere was clear - allowing us to see much more of the city than usual.  In fact, it also helped to create a superior mirage on the horizon, making parts of the city look as if they were upside down.

Visiting the Indiana Dunes National Lakeshore more than 45 weekends a year, we see plenty of interesting and new things - even the things we visit each time are never the same twice.

After the Burn

The Dune at The Burn Line

A recent controlled burn in the area removed most of the dry vegetation from the tops of these dunes along Lake Michigan. The area was once privately owned, and the buildings were removed about a year ago.  What a great piece of property this was, and the views from the homes was beautiful in all directions - woods to the south, marram grass dunes to the east and west, and Lake Michigan to the north.

 Aftermath of the Burn

The path to the lake can be seen now that the vegetation is gone. The dune at the right was spared this time around, probably to be burned in the next year or two.

Recent rains have started the recovery process here, the roots of the marram grass are sending up green shoots already.  Soon, this area will be lush with thick, green grasses, birds, dragonflies, and cicada wasps.

Superior Mirage

Superior Mirage on Lake Michigan

As the air warmed over Lake Michigan, a light fog developed on the horizon. This created a mirage of the distant Chicago skyline some 40 miles across the lake from our vantage point.

Called a superior mirage, it is created when cold air is near the surface, and warmer air is above. The atmosphere acts like a lens, inverting the skyline. If you look closely around the horizon, you will see the tops of some shorter buildings upside-down in the mirage.

Because of this mirage, objects that are usually hidden by the curvature of the earth can be seen above the horizon, only upside down. The Chicago skyline is usually visible from this vantage point, but the numerous other small buildings are never seen, unless displayed by a superior mirage.

Mirage Behind the Michigan City Lighthouse

Looking up the shoreline toward Michigan City, the lighthouse is visible, but generally nothing beyond.  It's unusual to see any land beyond the lighthouse, but the superior mirage along the horizon refracted the objects below the horizon, and displayed them above, just inverted.

An interesting effect created by the perfect weather conditions.
