The Cannon River Trout Lily Scientific and Natural Area shelters one of the largest populations of the endangered Minnesota dwarf trout lily, a delicate flower that blooms in early spring. This species is Minnesota’s only endemic flowering plant, found naturally nowhere else but in three southeastern Minnesota counties—Rice, Goodhue, and Steele—within the Straight and Cannon River watersheds. The dwarf trout lily, first discovered in 1870 by botany instructor Mary B. Hedges near Faribault, has a notably brief life cycle. Classified as a spring ephemeral, it sprouts, flowers, and produces food in early spring before its leaves fade by early summer as the forest canopy fills in. The plant primarily spreads asexually through offshoots, which is reflected in its scientific name, Erythronium propullans. Only rarely does it produce fertile seeds, relying on cross-pollination with the common white trout lily when it does, making its continued survival uncertain.

The falls is often dry during the summer, but it was fun to see it frozen in the winter on a cold day after some warm days.

I am fascinated by the geology and the poetic and metaphorical possibilities suggested by the merging waters of two watersheds. It was worth highlighting. Now, it’s up to me to generate the metaphors and poetic thoughts inspired by this highlight. The majestic Bald Eagle presiding over the confluence of the two rivers strikes me as poetic.

A long-time volunteer at the River Bend Nature Center informed me that during the summer months, this stream is barely a trickle, if it flows at all. It’s an amazing trick of nature how this small trickle can appear to be a massive waterfall. I thought it was well worth a highlight.

Great to see all year round. It is definitely the most busy place in the park, but well worth stopping down to see it. I especially enjoy going there a few times in the winter to see the falls frozen up. I see some nice pictures of it frozen in this collection.

I love this big rock. People like to spray paint on it unfortunately, but this rock kind of reminds me of the one in the Minnesota River Valley area, just walking along and all of a sudden a rock the side of a small school bus is sitting in front of you. This one is even cracked down the middle and you can walk through it.

At this point you have options to go east to take a break in Nerstrand or west to take a hike in Big Woods State Park. There is a nice little cafe in Nerstrand with great cookies.

The best time to visit depends on what you wish to experience. Early spring is ideal for witnessing the rare dwarf trout lily in bloom at locations like Caron Park or the Cannon River Trout Lily Scientific and Natural Area. Spring and fall offer vibrant foliage and more substantial water flow at waterfalls. Winter provides a unique perspective, with frozen falls and tranquil, snow-covered landscapes, particularly at Hidden Falls.
The Cannon River is a significant topographic feature, carving a path through Rice County and contributing to its diverse ecosystems. It forms part of the Cannon River Wilderness Area, which includes savanna and fen habitats, and its watershed is crucial for the survival of the endangered dwarf trout lily. The river's confluence with the Straight River is also a notable natural monument.
Caron Park is a natural area featuring the scenic Wellstone Falls, a natural limestone formation. It is also an important site for the rare dwarf trout lily. The park is located in a transitional ecological zone, offering diverse plant life. You can find more information about Caron Park on the Rice County website: ricecountymn.gov.
Yes, Nerstrand Big Woods State Park is a significant natural area that represents a remnant of the 'Big Woods,' a vast deciduous forest that once covered much of south-central Minnesota. The park's heavily wooded terrain offers a chance to experience this historically important forest ecosystem, along with features like Hidden Falls.
Rice County's landscape was significantly shaped by glacial activity, leaving behind well-preserved surficial sediments and landforms. The bedrock, often hidden by glacial deposits, consists mainly of marine sedimentary rocks, which are exposed in areas like the bluffs of the Cannon River and within parks such as Nerstrand State Park. This glacial history is evident in features like the Big Rock, a glacial erratic.
The Cannon River Wilderness Area spans approximately 850 acres, encompassing a wooded river valley, savanna, and fen ecosystems. It is another critical habitat for the rare dwarf trout lily. The area provides extensive hiking and horseback riding trails along the Cannon River, allowing visitors to experience diverse natural habitats. You can find more details on the Rice County website: ricecountymn.gov.
Falls Creek Park is a 61-acre natural area characterized by wooded hills, quarry rock formations, bluffs, and a spring-fed creek. Historically, it was part of the Cromer Stone Quarry.
