Using Fast Travel, please visit in the geovisualization at the indicated locations. You will not be sent to the exact location of the treeline. Part of the question involves you looking for the highest elevation of the dark green trees, using the Landsat Composite layer. There will be a complication -- that lava flows have periodically wiped out the vegetation, and then the trees gradually re-establish themselves. Thus, you are to walk to the highest dark green nearby. Write down the elevation, and also switch to precipitation and write down those values.
