Pronunciation: [dɹˈa͡ɪ ɡˈʌlt͡ʃ] (IPA) 
The word "dry gulch" is a Western term used to describe a narrow and steep ravine with no water running through it. The spelling is unique, with the "gulch" ending pronounced as "gʌltʃ". The "dry" aspect is straightforward, with the "d" pronounced as "d" and the "r" as "r". However, "gulch" is pronounced with a hard "g" followed by a "ʌ" vowel sound and a "ltʃ" ending, creating the distinct pronunciation of "gʌltʃ".
Dry gulch is a term used to describe a deep, narrow ravine or gully that remains dry for most of the year, mainly due to the scarcity of water or limited rainfall in the region. Often found in arid or semi-arid landscapes, a dry gulch typically lacks a consistent flow of water or a nearby water source, resulting in the absence of a permanent stream or river within its channel.
Characterized by steep sides and often a flat or rocky bottom, a dry gulch forms through the erosion of soil and sediment by intermittent or occasional rainfall. During periods of heavy rainfall or flash flooding, water can rush through the gulch, giving it the appearance of a temporary riverbed. However, once the downpour ceases, the gulch returns to its dry state, with no visible or continuous water flow.
Dry gulches can be found in various regions around the world, and their formation plays a significant role in shaping the landscape. They serve as natural drainage channels, carrying water away and preventing floods during times of high precipitation. Additionally, dry gulches may have historical or cultural importance, as they were often utilized as transportation routes or as hideouts by outlaws, giving rise to the term "dry gulch" being used casually to describe an ambush or attack in an unexpected or unfair manner.
The word "dry gulch" originates from 19th century American English, particularly in the Western frontier. It is formed by combining the word "dry", meaning without water or lacking moisture, and "gulch", which refers to a narrow and steep-sided ravine or gully.
In this context, "dry gulch" is a term used to describe a tactic employed by outlaws or criminals to ambush and kill someone by shooting them in the back while they are passing through a narrow and concealed passage, such as a dry gulch. This type of treacherous ambush was common during that time, particularly in the lawless regions of the American West.
Over time, "dry gulch" evolved to become a verb, meaning to ambush or betray someone unexpectedly, similar to how someone would be caught off guard in a deserted ravine.
