We have spent several days camped in Horace Cove. This has been a great place to camp while we have visited different rock outcrops. Unfortunately, we don’t have much reception here, so we haven’t been able to post updates. On Friday, Nick, Luke and I hiked to the interior of Patterson Island. We did this to explore the area closest to where the meteor hit. This is called a “highly shocked zone.” Geologists know that this area is closest to where the meteor hit by looking closely at the minerals in the rocks under the microscope. When a meteor hits it creates a shock wave in the rocks that led to high pressures. These high pressures change minerals like quartz and allow geologists to estimate the pressures that were created when the meteor hit.
The hike was much easier than the last time we tried to walk into the middle of the islands. The walking was easier because we started to think like caribou. Instead of walking through the thick forest, we walked along the streams and lakes. Some of the time we walked in the water and at other times we walked along caribou trails. We could tell that caribou had walked there because we could see their prints. We also found a caribou leg bone and a caribou antler along the trail.
On Saturday, we paddled our kayaks over to Sunday Harbor to investigate some of the jumbled rocks that formed when the meteor hit. After looking at the rocks, we walked up to the lighthouse on the southeast point of Patterson Island. The lighthouse is there so that ships sailing on Lake Superior know where the islands are even when the weather is bad.
When we returned to Horace Cove, we saw a sailboat at anchor. This was a very welcome sight because we knew Dave and two of our friends were onboard! We joined them for dinner and they gave us a bunch of fresh food. Dave, John and Dave G. sailed from Grand Marais, MN to meet us. It was a real treat to see familiar faces and get new treats to eat in the coming week.
