Summary of tracing particle arrivals for all exit fractures and the “golden fracture” through which 10% of the 10,000 tracing particles exit. A Histogram of arrival time, i.e. synthetic tracer test result, truncated at 11 days for clarity (bin width = 0.1 day). B Histogram of path lengths (bin width of 10 m). C Boxplot of arrival times, truncated at 11 days. D Boxplot of path length
