For Coeur du Deluge Chapter President Tony Lewis, an opportunity to lead a Sandpoint 4th grade class in a learning unit on “how Idaho landforms were created” came up suddenly on Oct. 8th. Terese Luikens, the 4th Grade Teacher at Southside Elementary School had 19 students wanting “an actual field trip where you can show and tell us about how glaciers formed some of our lakes.” 3 days later Tony was in front of Mrs. Luikens’ 19 excited and exuberant students, struck by how 4th graders react to rocks and a guest presenter. Hands were up, even before his “Landforms of North Idaho: How They Were Formed and What Caused Them” presentation started. How can you NOT be swept up in their enthusiasm and amazed by their unending questions, some of which are actually related to the topic? They were more excited when he left their school than when he had arrived, and the field trip was happening two days later!
Unfortunately, the weather didn’t cooperate. It was cold and windy with a chance of rain when they met at the Pavilion at City Beach in Sandpoint, ID at 10 AM. Were these 4th graders put-off by a “little” inclement weather? Of course not, but they did seem disappointed when told that they were not allowed to go swimming. Hands up again, asking questions, wanting to show where they lived, where we were and where we were going on the maps and images Tony had. After an hour reviewing what was talked about on Monday, with more information about David Thompson, the Ice Age Floods, glaciation and the Purcell Trench and how different lakes (Round, Cocolalla, Mirror and Pend Oreille) were formed, we all loaded up for a drive through the bottom of the Purcell Trench, the Pack River Delta and finally to the Geologic Overlook just one mile east of Hope, ID.
Before leaving the bus, the students were given their boundaries and they abided. Although the clouds covered some of the scenes, we could see the steep-faced Green Monarch Mts. where the Purcell Trench Lobe glacier divided into four sub-lobes. One of the sub-lobes went up the Clark Fork River, plugging up the drainage basin and causing Glacial Lake Missoula. Another lobe moved southward, deepening the basin now occupied by Lake Pend Oreille. The students seemed to enjoy viewing the wide-expansive scene of ‘the place where the Ice Age Floods started’. The field trip ended when it started to rain, and the drive back to Sandpoint was uneventful, although I was admonished, in a nice but serious way, for walking up and down the aisle because it was dangerous and “I might break my back!” I agreed and took my seat. It was a fun learning experience for me, and I hope it was for them also.
