The alpine growing season is six weeks
Above the timber line you find the Alpine Tundra. Timber line is determined by temperature. When the average summer temperature drops below 55 degrees the pine trees cannot grow. Today the temperature was 53 degrees and wind chill dropped it to 45 degrees.

Bob telling us about the sunflower.
Plants up here must adapt to the limited growing season. The Sunflower stores energy during the brief growing season for 10 or 12 years, then blooms and sets seeds.
