Context examples:
Scientists use the term "gully" for features on Mars that share three characteristics in their shape: an alcove at the top, a channel, and an apron of deposited material at the bottom.

Dundas and collaborators used the High Resolution Imaging Science Experiment (HiRISE) camera on MRO to examine gullies at 356 sites on Mars, beginning in 2006.

Overcoming a strong repugnance, I tore open his shirt at the neck, and there, sure enough, hanging to a bit of tarry string, which I cut with his own gully, we found the key.
(Treasure Island, by Robert Louis Stevenson)
Researchers from the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland, examined high-resolution compositional data from more than 100 gully sites throughout Mars.
(Mars Gullies Likely Not Formed by Liquid Water, NASA)
Thirty-eight of the sites showed active gully formation, such as new channel segments and increased deposits at the downhill end of some gullies.

A few small coins, a thimble, and some thread and big needles, a piece of pigtail tobacco bitten away at the end, his gully with the crooked handle, a pocket compass, and a tinder box were all that they contained, and I began to despair.
(Treasure Island, by Robert Louis Stevenson)
The lack of sufficient water to carve gullies has resulted in a variety of theories for the gullies' creation, including different mechanisms involving evaporation of water and carbon dioxide frost.
(Mars Gullies Likely Not Formed by Liquid Water, NASA)
Although the findings about gullies point to processes that do not involve liquid water, possible action by liquid water on Mars has been reported in the past year in other findings from the HiRISE team.
(NASA spacecraft observes further evidence of dry ice gullies on Mars, NASA)
The team had shown there was seasonal activity in gullies — primarily in the southern hemisphere — over the past couple of years, and carbon dioxide frost is the main mechanism they suspected of causing it.
(Mars Gullies Likely Not Formed by Liquid Water, NASA)
The findings in this latest report suggest all of the fresh-appearing gullies seen on Mars can be attributed to processes currently underway, whereas earlier hypotheses suggested they formed thousands to millions of years ago when climate conditions were possibly conducive to liquid water on Mars.
