Sinkiuse-Columbia
indigenous people of the Northwestern USA
The Sinkiuse-Columbia are a Native American tribe so-called because of their former prominent association with the Columbia River. They speak the Columbia-Moses language and are an Interior Salish people whose nearest relatives are the Wenatchis and Methows.
Name
The Sinkiuses call themselves .tskowa'xtsEnux, or .skowa'xtsEnEx (meaning has something to do with "main valley"), or Sinkiuse. They apply the name to other neighboring Interior Salish peoples, potentially originating from a band that once inhabited the Umatilla Valley.
Other names the Sinkiuse-Columbia people were known by include:
Bo'tcaced, by the Nez Percé, probably, meaning "arrows" or "arrow people."
Papspê'lu, another Nez Perce name, meaning "firs," or "fir-tree people."
Isle-de-Pierre, name conferred by the French Canadian employees of the fur companies, meaning "rock island", perhaps for a band of the tribe.
Middle Columbia Salish, so called by Teit (1928) and Spier (1930 b).
Sa'ladebc, probably the Snohomish name.
Suwa'dabc, Snohomish name for all interior Indians, meaning "inland people," or "interior people."
swa'dab.c, Twana name for all interior Indians, meaning "inland people."
swa'namc, Nooksack name for all interior Indians, meaning "inland people."
Ti'attluxa, Wasco Chinook name.
Ethnography
The homeland of the Sinkiuse was based on the Columbia River from Crab Creek upstream to the Wenatchee River and centered on Moses Coulee. In 1870, Winans placed them "on the east and south sides of the Columbia River from the Grand Coulee down to Priest's Rapids."
Hale classified the Sinkiuse as a division of the Pisquows with population 355 in 1905, 299 in 1908, 540 (with others?) in 1990.

Why this record matters
“Sinkiuse-Columbia” is worth following because a concise public description often conceals a longer documentary argument. Here, Sinkiuse-Columbia, indigenous and people provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Oct 19, 2025. The linked authority identifier is Q918568. The Library of Congress control number is sh85122892. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1928, 1930, 1870 and 1905.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
