Umbes

Could you specify what "umbes" refers to? It could denote a place, a river, a people or culture, a term in a particular language, or something else entirely. If you can provide the region, context, or intended meaning, I can write a concise, neutral wiki-style article (under 300 words) about it. If you’d prefer, I can also draft a generic disambiguation-style entry that outlines possible senses with minimal detail.
