Hi Chad, your assumption is incorrect. We had knots in the end of our ropes for each rappel. You couldn't see them from where you were. We were able to rappel safely down but loose rock on the walk down swept Amy over a ledge 20-30 feet.
I'm sorry you're connected with the accident, and it was nice to meet you at the belay station. The accident happened after we safely rappelled the route, anchor to anchor. We were a party of 5, so the comms you heard were us letting the party of two ahead of us know that we had decided to bail off.
Thank you, sincerely, for responding to the SAR. We were blown away by the response from the community and a contingent will be joining me to return to the accident site. Feel free to get in touch - please. It helps for me to talk about it and it helps others to get detail.
