This happened last week, but I didn't get a chance to write it up until now. I did not witness the fall but was on scene to assist.
On Saturday morning 1/25, a climber (I think Tina was her name) was leading one of the routes on the far left side of Texaco Amphitheater. She was in a party of three, and they were the second group to arrive at the crag that morning. I was the third group to arrive right behind them. After exchanging pleasantries and discussing what they were planning to climb, I informed them that I was going to hike/solo up to the top of the cliff and drop a toprope to the right of their intended route. Tina mentioned that this was her first ice lead of the season.
While I was at the top of the cliff and preparing to rap back down to the base, Tina fell on lead. I obviously couldn't see it, but my understanding is that she was 4-8 feet off the ground when she fell and did not have any screws placed to arrest her fall, which resulted in her hitting the deck. The base of the route she was climbing was sloped and icy, and she either landed or stumbled awkwardly upon hitting the ground, injuring her right ankle. She was sitting on the ground after her fall but in visible pain. All of the climbers in the area (there were about 8 or 9 of us by that time including myself) stopped what we were doing to assist (I rapped down to the base).
Another climber there performed a quick assessment of her injuries and built splint around her right ankle, which he believed was broken. Tina's climbing partners packed up their gear, and they attempted to get Tina out accompanied by 4 or 5 other climbers. Tina was initially sliding on her butt down the trail and someone provided a belay to prevent her from tumbling down the steep parts, but progress was slow going. Eventually they decided to carry her out with someone running back to their car to use the top of a Thule cargo box as a litter. The climbers that assisted did not return for several hours (I did not hike out with them), but they made it out okay.
I would note that the ice was highly variable that day, and most of it was on the difficult/sketchy side in terms of conditions. I noticed that one of the climbers that helped in the carry out attempted two leads in the afternoon and backed off both of them, which I think was smart.
