Johnna Austin (NPS Ranger)

Abigail ‘Abby’ Olson (NPS Ranger)

Ranger Abby has been in love with water all her life; lakes, streams, ponds, rivers, and especially waterfalls. Over the last decade as a ranger, she has learned a lot about how the water of the mighty Mississippi interacts with the land, animals, plants, and people around it. She's excited to share her stories and knowledge with your students about the geology and otters of the Mississippi River or take a deeper look into the job of a Park Ranger at any National Park.

Stephen Walker (Mississippi Park Connection)

Stephen was born in Minnesota, and spent much of his youth exploring the Northwoods of the state, where the Mississippi River has its headwaters. Says Stephen: “I swam in the Mississippi countless times as a kid, I’ve camped on islands in the middle of the river, and I’ve walked across it frozen in the winter– it has generally weaved its way around most of my life. In 2022, I saw all 2,340 miles of the Mississippi River, when I took a canoe and paddled from Lake Itasca to the Gulf of Mexico. That took me 97 days!” Stephen has also worked at Crater Lake National Park, in Oregon. Stephen is so excited to share his enthusiasm for the Mississippi River, and its history, geology, and ecology with curious minds.
