Hi Brian
One assumes that the inclusion of Unknown in the database is the result of a failure to realise that HKG started to the right of BB and thus appears after it in the guide, although its only fixed gear - and obvious visibility - is in the upper part to the left of that route. So it was always just the top half of HKG with a direct approach up the rubble! As the updated HKG entry suggests, "9 feet right of Bogger Bob" puts you at the old, bold start of Shin Gi Tai - the arete - rather than the current bolted line which uses the original start to HKG. Essentially, the starts of HKG and SGT have now been swapped, thereby retaining some bold climbing for the former - although not on its original line.
