Hi Dave,
No, I didn't see anyone who had summited via the MR.
I spoke to the Ranger the prior day and he said a few people planned to go up the MR on Sat and Sunday and gotten permits. From what I understood, there was loose snow and ice on many sections from Iceberg Lake up including the final 400. Given the snow/ice conditions, I opted to do the Main Trail, where such snow and ice has less severe consequences.
I actually only saw one other person that I knew summited that day, with 2-3 other possible summiters all from the Main Trail as far as I could tell. There were 6-7 other people who I saw hiking up, but I didn't see them after 11-12k, so assume they turned around or were planning something else.
