Why is "Minor tombs in the Valley of the Kings" trending?

Wikipedia Overview

The majority of the 65 numbered tombs in the Valley of the Kings can be considered minor tombs, either because at present they have yielded little information or because the results of their investigation was only poorly recorded by their explorers, while some have received very little attention or were only cursorily noted. Most of these tombs are small, often only consisting of a single burial chamber accessed by means of a shaft or a staircase with a corridor or a series of corridors leading to the chamber, but some are larger, multiple chambered tombs. These minor tombs served various purposes, some were intended for burials of lesser royalty or for private burials, some contained animal burials and others apparently never received a primary burial. In many cases these tombs also served secondary functions and later intrusive material has been found related to these secondary activities. While some of these tombs have been open since antiquity, the majority were discovered in the 19th and early 20th centuries during the height of exploration in the valley.
