What procedure could a pilot use to navigate under VFR from one point to another when ground references are not visible?

Explanation

PHAK Chapter 16 defines dead reckoning as navigation solely by computations based on time, airspeed, distance and direction, which works when ground references cannot be seen. Pilotage depends on visible landmarks, and VFR flight is permitted above or out of sight of references as long as VFR weather minimums are met.
