Import Outlook 2010 calendar to iCal #

This worked:

Export calendar as PST from Outlook 2010
Import PST into Outlook 2011
Sync Outlook 2011 calendar with iCal (Outlook 2011 > Preferences > Sync Services > check "Calendar". Took several minutes for the sync to complete, with no progress indicator other than the fan going crazy.)
Disable Sync Services if desired

These didn't work:

O2M exported an ICS file from Outlook 2010, but the resultant data was a total mess - 20 events a day instead of the expected 4 or 5. Have had good luck with O2M in the past.
MessageSave also exported an ICS file from Outlook 2010, but attempting to import it would crash iCal every time. Have had good luck with this product before as well.
Export calendar PST from Outlook 2010 > import into Outlook 2011 > Calendar > File > Save Calendar. Very promising (and unexpected) export option which generates an ICS file directly from Outlook 2011. Sadly, attempting to import it into iCal returned: "Import Failed - Multiple validation errors occurred."
