CACTUS IN MINNESOTA?
Yes, actually two species of Prickly Pear Cactus occur in southwest Minnesota…Opuntia fragilis and Opuntia macrorhiza. And Blue Mounds State Park is a great place to see them for yourself. No, not giant cartoon-type cactus but a low-growing cactus with GORGEOUS and HUGE yellow blossoms. They should be blooming now! To make sure, call the park office in advance.
If you squint, you can almost imagine a time when tallgrass prairie covered the endless landscapes of southern and western Minnesota. And Purple Prairie-Clover (Dalea purpurea) was part of that rich mosaic of prairie wildflowers.
This species is a legume with a taproot that may reach down 6 feet into the soil! This root system helps prevent soil erosion. It is a true prairie plant that has evolved with fire, and does not tolerate shade. Pronghorns are even known to eat it.

A looming thunderstorm provides a dramatic backdrop to these grazing Bison. Don’t let me mislead you…There is a fence around the entire herd, and they are not always visible to park visitors.

In 1961, the park added three bison from the Fort Niobrara Wildlife Refuge near Valentine, Nebraska to start the present bison herd. Today, the Blue Mounds’ herd is maintained at more than 100 bison.

Notice the deeply cut leaves and extemely reflexed ray petals of the Pinnate Prairie Coneflower (Ratibida pinnata) (sometimes called Gray-headed Coneflower). To emphasize the incredible five-foot height of this prairie native, I crouched down with my wide angle lens and put the flowering heads “in the clouds” so to speak. This photo would not have had much impact if taken at “eye-level” with the flowers.

Gray Partridge, the bird formerly known as Hungarian Partridge, are not easy to find…anywhere. So I was very fortunate to run into this breeding-plumaged male near the park. They are one of the few birds that utilize seemingly barren crop fields that surround the park. I lost the original of this image when I dropped a hard drive years ago, but fortunately I printed a 4×6. This is a scan of that 4×6 print.

A Turkey Vulture soars over the prairie at Blue Mounds State Park. This is the same tree and Sioux Quartzite outcrop as in another photo in this post.

Cliffs can be habitat too. This Great Horned Owl has made a home of the Quartzite cliffs on the east side of the park. Hiking trails parallel the cliffs along the base and also on top of the bluff.

We rarely see Great Horned Owls in flight during the day. So when this guy took off, I held down the shutter. He/she then obligingly banked to reveal the full spread of its large wings and a full tail fan. The fact that he/she peeked over his/her shoulder at me was a bonus.

RARE FIND
I found this singing Rock Wren at the top of a cliff several Junes ago. The closest this western bird regularly breeds to Minnesota would be the Black Hills of South Dakota, over 300 miles away! Unfortunately, this guy did not find a mate here and likely moved on.

Some outcrops of Sioux Quartzite are more red than others, and this one also has excellent patterning with crusted green lichens. This scene is near the drive up to the Interpretive Center. The Box Elder (I think it’s a Box Elder) adds to the composition that might be a little boring without it.

A dawn rainstorm spawned a sunrise rainbow. The clouds, 180 degrees from the rising sun, lit up a beautiful pink color. In order to get the entire arc of the rainbow, I used my 10mm lens (equivalent of a 16mm lens as it was on my camera with a 1.6 crop factor) and placed the Bison underneath. I tried everything I could think of to get him to lift his head, but to no avail. I still like this unique image.

Bison rarely run, so when I saw this stampeding herd, I quickly switched my camera settings to Shutter Priority 1/30 of a second and panned with them. I got one shot that portrays the speed of these huge animals.
