Hiking Trails |

The north parking area is at the corner of a woodland that has a dense, at times impenetrable shrub layer. Two trails lead from this parking area into the SNA. The first, a broad, open trail that doubles as a utility road, leads east to restored prairie on former agricultural fields. At that point the trail turns south and follows the top of the bluff, eventually reaching the south parking area. A second, much more interesting trail leads south through the western edge of the woodland. It emerges at the edge of the site’s only shallow lake and near a tunnel under the railroad tracks that connects the north and south sections of the SNA. A well used trail leads west from the south parking area to the railroad tracks. There are several other trails, really well worn footpaths, on this site, indicating that this metro SNA is often used by the public. On a recent trip there were no cars at the north parking lot when I arrived at 10:30 am on a Sunday. There were five cars in the lot when I left at 3:30 pm. |

Oak Grove
In stark contrast to the dense woods near the north parking area, the wooded section at the southwest corner of the SNA is an oak grove. There is an canopy of tall oak, hackberry, and other trees, but there is no shrub layer. This area is often flooded in the spring.
Railroad Prairie
A busy section of the Burlington Northern and Santa Fe Railway separates the north and south sections of the SNA. A tunnel beneath the tracks at the west boundary connects the two sections. Two-thirds of the railway between the sections is designated railroad prairie.

About
Apr 2, 2020 Take a hike out onto the high terrace at Grey Cloud Dunes SNA. You’ll see a spectacular view of the Mississippi River. It’s a treat any time of year, but was especially nice in November, when this video was taken during a seed collection event on the site. This site was designated on December 30, 1998. mndnr.gov/snas/sna01101 |

About
June 14, 2011 This video represents what happens when to much deet is ingested with Nicotine. After seeing a bizzilion sparrows, one gets a bit punchy. Facts were not checked after the release of this video. It takes place at Grey Cloud Dunes Scientific and Natural Area. This unique prairie is located on sandy terraces 60 and 110 feet above the present Mississippi River. Formed by the out-wash of the greatly enhanced glacial Mississippi, sand dunes resulted in crescent shapes or blow outs from SW winds. The place is a damn sparrow jamberoo, with over 8 different species. Plus isolated scrub is colonized by Orchard Orioles, Brown Thrashers, Bells Vireos, Alder Flycatchers, Eastern Meadowlarks and Yellow-Billed Cuckoos among many other |
