Roseberg, OR





It is still pretty warm here. We have heard that it is cold in Minnesota. I hope you are all well!

Ranger Dave told us that Crater Lake is a caldera lake in the U.S. state of Oregon. It is the main feature of Crater Lake National Park and famous for its deep blue color and water clarity. The lake partly fills a nearly 4,000 feet caldera that was formed by the collapse of the volcano Mount Mazama.

On June 12, 1853, John Wesley Hillman was reportedly the first European American to see what he named "Deep Blue Lake" in Oregon. The lake was renamed at least three times, as Blue Lake, Lake Majesty, and finally Crater Lake.

Crater Lake is known for its famous piece of driftwood named the "Old Man of the Lake." It is a full-sized tree that has been bobbing vertically in the lake for more than a century. Due to the cold water of the lake, the tree has been rather well preserved.

Ranger Dave told us about the Rain shadow too. We did an experiment that explained the rain shadow and showed us the three states of matter in action!!

Journal Update:

Today we saw a ranger. His name was Ranger Dave. He showed us an experiment how something frozen turns to a liquid and then a gas. Before you knew it there was no water in the pan.

There’s a lake that once was a volcano. In that volcano there is a log in the water that’s pointing straight up like a bobber. They call it “The Old Man in the Lake.” There is also Wizard Island.
