- On Mosquito Lake Road, you can visit all three forks of the Nooksack River. In the north, Mosquito Lake Road exists Washington State Route 9 in Welcome, Washington. There it crosses the North Fork Nooksack River. Incidenally, the North Fork Road immediately after Welome is the primary access point for Racehorse Creek and the fossil fields. Mosquito Lake Road continues until it crosses the Middle Fork Nooksack River about half way to Acme, Washington. In Acme, the road runs alongside the South Fork NookSack River for a short distance before reaching Washington State Route 9 again.

- Absolute magnitude (Wikipedia)
In astronomy, absolute magnitude (M) is a measure of the luminosity of a celestial object on an inverse logarithmic astronomical magnitude scale. An object’s absolute magnitude is defined to be equal to the apparent magnitude that the object would have if it were viewed from a distance of exactly 10 parsecs (32.6 light-years), without extinction (or dimming) of its light due to absorption by interstellar matter and cosmic dust. By hypothetically placing all objects at a standard reference distance from the observer, their luminosities can be directly compared among each other on a magnitude scale. For Solar System bodies that shine in reflected light, a different definition of absolute magnitude (H) is used, based on a standard reference distance of one astronomical unit.
