Locating and extinguishing burning subsurface fuels can be quite challenging due to several factors. Subsurface fuels often consist of organic materials like roots and decaying vegetation that can smolder and create hidden hot spots well below the surface. These types of fuels may not be easily visible, making detection difficult. Fire can spread through these subsurface materials without showing visible flames on the surface, complicating efforts to identify the full extent of the fire.

When it comes to extinguishing these fires, conventional methods may be less effective because water or fire retardants might not reach the burning material effectively, and the materials can retain heat, potentially leading to re-ignition if not properly extinguished. This necessitates a more comprehensive approach, often requiring hand tools or specialized equipment to turn over the soil and expose the burning material.

This difficulty in both locating and successfully extinguishing subsurface fires underscores why the scenario is classified as hard in both aspects, making this option the appropriate choice.
