Day 6

We got up early and we went into the forest of the Siberian Taiga, as we explored we saw many Jack Pine, the Douglas fir, and the Siberian Spruce. We studied the Siberian Spruce for a bit as he noticed its massive towering height. We also took notice its density of the trunk of the tree. So we decided to measure it quickly with measuring tape to find the diameter, which was 1.5 meters. We continued our journey saw many interesting specimens until the sun begun to past the horizon and head back to the hotel.
