Tahltan (or Nahanni) refers to a Northern Athabaskan people that live around Telegraph Creek, Dease Lake and Iskut.

The modern history of the Telegraph Creek and Dease Lake area dates back to the 1860s and 1870s with the Stikine and Cassiar Gold Rushes.

As early as 10,000 years ago, the Tahltan people used obsidian from the Mount Edziza volcanic complex to make tools and weapons for trading material.

[9] Author Edward Hoagland wrote extensively about Telegraph Creek in his 1969 book Notes from the Century Before: A Journal from British Columbia in which he reveals the presence of a high level of ghost activities.

The area surrounding Telegraph Creek holds five British Columbia Provincial parks: The road between Dease Lake, BC and Telegraph Creek is beautiful but rough, with 113 km (70 mi) of gravel, steep gradients (up to 20%), narrow passages along canyon walls with no guardrails, and sharp-angled switchbacks.
