Boötes III has σ_v ≈ 1.7 km/s, a recent ~9.5 kpc pericenter on a polar eccentric orbit, and is actively tidally disrupting, with debris broadly consistent with the Styx stream.
DESI data on the GD-1 stream identifies a thin cold core and a hot cocoon with 30% of members whose dispersion is consistent with 11 Gyr of dark matter subhalo heating.
