Corporate jet pilot reported the published traffic pattern for 4B6 places aircraft too close to surrounding terrain.

Narrative

The airport 4B6 Ticonderoga has a published VFR right downwind for Runway 20 and a left downwind pattern for Runway 2. High terrain to the west of the airport and the airport sitting in a bowl of hills to the west make a visual approach very close to the terrain. If however the published pattern was to the east; no terrain conflict exists. The issue at play is being able to get a stabilized approach on final for the runways with the close in terrain. However if the procedure CHANGED to allow for a left downwind to runway 20 and a right downwind to runway 02; no terrain conflict exists. In the current process; a right downwind to 20 makes a close in turn to final around the terrain. If you extend that visual downwind beyond the mountain bowl to the north; the aircraft would be able to have a longer stabilized final approach but a descent on right base would keep the airport from view. I have asked about why the VFR pattern is published that way and the response is to avoid the paper plant on a east side downwind. However a downwind over the river like Lake Champlain would remove the terrain issue; and the limited final approach to runway 20. This would provide the greatest safety. I have flown into this airport in a very light jet; turboprop; and twin piston aircraft for years; and would hope to see the visual procedure here changed before someone has an incident.
