The cause of her death was the unusual congestion near the summit of Mt Everest because of a narrow climbing window made narrower by severe weather conditions and the Nepal government issuing permits to several hundred climbers. At least 11 climbers — many of them veteran mountain climbers like Dash — from Nepal, Europe, United States and India died during the 2019 climbing season in April and May 2019. Donald Cash from Utah in the United States and Anjali Kulkarni from India were among those who died in the same week as Dash.
