  A conical void in the Galactic HI within the Perseus arm has been proposed to
be a chimney. However, Halpha data suggest that the structure may be closed at
higher latitudes and therefore is a superbubble rather than a chimney. Recent
observations have extended our view of the HI and the radio continuum emission
to higher latitudes, up to 8 degrees;. The new images show the HI structure to
be open at the top and a small filament suggests recent breakout. The conical
shape of the structure is not easily explained by superbubble models.
