OK, the word may be a little confusing, but phenology is easy. Actually you probably do it almost every day without even knowing!
Simply observe the environment around you, then record what you see or measure.
When is the first snow-day?
When do you get to put on shorts for the first time of the year?
When do you see the first robin!?
Record YOUR observations in the Explore Zone and they will be added to the Observations Map. Compare YOUR information with actual data from Team members on the trail, Basecamp and other student explorers.
