Today when I was returning home I decided to take a walk along the river and take some pictures from the other side of the river.
To my astonishment I noticed that there was something strangely shaped in the sky.
Initially I was thinking that it could be a cloud in a different format, but when I started to zoom in I realized that the origin was from the ground towards the sky.
This led me to think that it could be a forest fire since here in Portugal it's summer and it's always a time when several forest fires occur. However, when I got home there was no news about this event so I still don't know what caused this.
Here are some photos documenting what happened.
