There seems to be an uptick in Political comments in recent months. Those of us who are long time members of the site know that Political and Religious content has been banned for years. Nothing has changed. Please leave all political and religious comments out of the forums.
If you recently joined the forums you were not presented with this restriction in the terms of service. This was due to a conversion error when we went from vBulletin to Xenforo. We have updated our terms of service to reflect these corrections.
Please note any post refering to a politician will be considered political even if it is intended to be humor. Our experience is these topics have a way of dividing the forums and causing deep resentment among members. It is a poison to the community. We appreciate compliance with the rules.

Those remind me of standing leticlars in some ways. A good idea is to stay away from the area they are in.
This is a lenticular.............

not even close !!
We get "roll clouds" occasionally along the eastern side of the Rocky Mountains, the "Front Range", just where the mountains drop off onto the western end of the Great Plains. The article says these may be similar.
Wulf190 is correct in saying you wouldn't want to get close to them. When we have roll clouds along the foothills the turbulence is usually extreme. Dogknot, we do get lenticulars here also, I believe Wulf190 maybe was referring the possible turbulence, or also possibly how the clouds are formed -- maybe a "mountain wave".
Looks like the photographer was in a Skyhawk or Skylane (or Stationair), which is what I fly. You don't want to get anywhere near roll clouds or lenticulars in a light plane. Its about like being that little ball in the spray paint can when you shake it.
We do get mountain wave turbulence even without the clouds, so we have to pay attention to these special wind conditions when we fly, even if there are no visual signs of mountain waves.

someone cue the foil hat guys so they can post theories on how those clouds are evidence of the government testing bilogical weapons on the unsuspecting public, or caused by global warming. 
I have only seen a roll cloud once in my life and it was an awesome sight as it was running in front of a major thunderstorm cell.
I am a former trained (volunteer) severe weather spotter for Environment Canada and as we live in the thunderstorm capital of Canada we get called upon to provide accurate sighting reports which are then used to provide warnings for others further along the predicted storm path.
In the above case I was attending a public function where the Amateur Radio Emergency Service branch I was the head of were providing communications support to the organizers. As the storm cell approached the sky in the west turned a very dark grey (almost black) that was tinged with green (not a good sight at all as that usually signifies a very powerful and dangerous storm condition). Running in front of the cell was a beautiful roll cloud that looked a vivid white in front of the dark background. As it approached we could see the cloud rolling in the opposite direction to the way a wheel would roll if travelling in the same direction. It truly was a jaw dropping sight and one of nature's wonders.
Once the roll cloud passed overhead we had to scramble to get the public under shelter and when the storm hit it was a nasty one with lashing winds, driving rain and hail and almost constant lightning.
