Without stopping to take a look around, we can sometimes miss the transition of our surroundings from summer to autumn. But just in case you’ve been watching the trees change colors, here’s a list of photos that compare various locations before and after they change into their autumn colors.

Besides the nip in the air, the scarves, and the delicious autumn fruits and vegetables, the changing leaves are probably the greatest sign of autumn that there is. Chlorophyll, which is the green pigment in leaves that produces energy for trees, gradually breaks down in the fall, revealing the many other colors that also exist in leaves. That’s where we get the rich browns, oranges, yellows and reds that we associate with the season.
