At the end of every quarter the Sifter highlights the top 25 ‘Pictures of the Day‘, culminating in an epic Top 100 at the end of the year (check out the ‘Top 100 POTDs for 2012‘).

It’s hard to believe there is only two weeks left in 2013! I can’t wait to see what the new year will bring. Below you will find the fourth and final installment of this quarterly compilation. All credit goes to the individual photographers and their inspiring visions of our beautiful planet.

*Please note the photographs themselves were not necessarily taken in 2013, they just happened to be featured as a POTD on TwistedSifter. The pictures are also listed in reverse chronological order. There is no ranking amongst the photos, they are all incredible 🙂
