Do the same as before and find the opposite side of the crown, and drive a second stake to mark it. You now have marked the widest and narrowest dimensions of the crown. Measure the number of feet between the stakes marking the crown's widest dimension and write it down. Measure the number of feet between the stakes marking the crown's narrowest dimension. Add the two numbers together, divide by two, and the result is the tree's average crown spread.
Photograph Make a map of the tree's location.
Draw it on a separate piece of paper and enclose it with your nomination. Use standard descriptors on the map, such as township and range, section and subsection, and include a directional arrow pointing north. Indicate prominent landmarks such as powerlines and bridges. Add nearby roads, trails and waterways.
