Abstract We use Green Bank Ammonia Survey observations of NH 3 (1, 1) and (2, 2)
emission with 32''FWHM resolution from a∼ 10 pc 2 portion of the Cepheus-L1251
molecular cloud to identify hierarchical dense gas structures. Our dendrogram analysis of
the NH 3 data results in 22 top-level structures, which reside within 13 lower-level parent
structures. The structures are compact $(0.01\,\mathrm {pc}\lesssim {R} _ {\mathrm
{eff}}\lesssim 0.1\,\mathrm {pc}) $
