I can not speak for the North Ridge of the Grand. As for Teewinot it is in that mid-season condition not quite all snow or all rock. The two prongs are mostly snowed in. The upper Koven as well as the summit bench is still covered in snow. Good Luck!
i was on Owen 2 mondays ago, and it was real filled in with snow. Met some fellas on the koven col who were doing the cathedral traverse and they followed our steps to the summit, and they were both pretty surprised with the amount of snow everywhere, compared to previous years. Have fun, good luck!
