In Spanish, "labor" means "job" or "task," depending on the context. The suffix -ito/a, or -cito/a, if it comes after a consonant, is a diminutive, so in this case "laborcita" would, very literally, mean something like "little task." Taken out of context, it doesn't make much sense, but I'm guessing it must be related to the history of the canyon somehow.
