The super monarchs can travel 50 miles or even 100 miles per day, but their wings don’t do all the work. They often ride on thermal air currents, sometimes as high as 1 mile above the ground.

The monarchs you see at this time of the year are truly special, part of a 'super generation' that's different than the three generations that preceded it.

Our waters are home to many duck species, but none as ornate as the wood duck, which looks like a duck dressed up for a special occasion. As is common among ducks, it's the males that are most striking, sporting bold white stripes along with a chestnut breast and flashes of emerald green. Females are more subdued, but with blue patches on their wings and a noticeable white ring around their eyes.

It should come as no surprise that wood ducks love trees, but that's not all that is unique about them.

Joliet is known as both the City of Steel and the City of Stone, and the story of the city's industrial past is told along the trail traversing the remains of an iron and steel plant at Joliet Iron Works Historic Site on the city's east side. The facility was operational from the late 1800s to the early 1900s, and the Forest Preserve District acquired land for the 52-acre site between 1991 and 1997.

Today, the ruins of the iron works provide a glimpse into the city's past, with visitors being able to walk the 0.59-mile trail with interpretive signs installed along the way detailing the work done at the site and the lives of the people employed there. The foundations on the site are all that remains of the once bustling steel mill, but walking the site gives a feel for the industry that shaped Joliet into the industrial center that it once was.

The hoot of the great horned owl is the quintessential hoot. They call out hoo-h-hoo-hoo-hoo into the night, with males and females sometimes singing back and forth to one another.

Always yield to oncoming traffic at intersections, and follow all posted signage. Remember, too, that some Forest Preserve trails are equestrian trails, so horses may be present along your ride. When passing a horse, cyclists should rely on their voice to announce their presence rather than bells or horns, which could spook a horse.

The trails can be crowded on nice days, so make sure you're being a good neighbor by practicing proper trail etiquette.
