Slow Heart Beat (Bradycardia) An abnormally slow sinus heart rate is called the âsick sinus syndromeâ and, if severe, results in symptoms of fatigue. In some such cases a permanent pacemaker is needed to be implanted to generate a normal heart rate. Many people with sick sinus syndrome also develop atrial fibrillation.
Petrified wood (from the Greek root petro meaning rock or stone; literally wood turned into stone) is the name given to a special type of fossilized remains of terrestrial vegetation. It is the result of a tree or tree-like plants having completely transitioned to stone by the process of permineralization.lements such as manganese, iron, and copper in the water/mud during the petrification process give petrified wood a variety of color ranges. Pure quartz crystals are colorless, but when contaminants are added to the process the crystals take on a yellow, red, or other tint.
There's only one trail in the park. Pick up a nature trial guide at the trailhead kiosk. The short trail leads up a steep hill and features some colorful petrified wood (please do not collect). The wood is the remains of ancient conifer trees that existed when the area was considerably wetter and more tropical. 0.75 mile optional spur trail leads down a hill side to some of the better examples of petrified wood in the park. Rating (1-5 stars): The author and his wife visited the park mainly to get a shower (the showers are nice). The petrified wood is interesting, but not worth the $5 entry fee.
