North Kaibab is considered the most difficult of the Grand Canyon’s major inner trails, reports said.
An emergency call about a hiker in distress on the North Kaibab Trail was received by the Regional Communications Centre at approximately 1:55 pm. But, soon after the call, the hiker became unresponsive. The search and rescue personnel responded to the call via helicopter but faced difficulties fully landing the aircraft, given the steep and rocky terrain.
Their attempts to resuscitate Varma failed, and he was pronounced dead, KSL-TV station reported.

His body was transported to the Coconino County Medical Examiner's Office in Flagstaff, which is investigating the incident together with the National Park Service, according to the KTAR news channel.
Although the precise cause of Varma's death is not yet known, Baird said it was likely that heat was a factor.
On Saturday, temperatures within the inner canyon were over 100°F (37.7°C), according to the report.
In the summer, temperatures on exposed parts of the trail can reach over 120°F (49 °C) in the shade.
The report said North Kaibab is the most difficult of the Grand Canyon's major inner trails.
