February 19, 2018 Winter into Spring

金山巨石群 冬期120日間終了の光

Kanayama Megaliths 120 Days of Winter Ends 2018 21519

This is our excerpt from the blog posted by the Kanayama Megaliths Research Center at  http://blog.livedoor.jp/kanayama_tour-kanayamamegaliths/archives/1070157722.html on 2018.02.22. 

The face of the Sekimen stone in Iwaya-Iwakage is lit by a spotlight for five days from February 15 to 19. February 19 marks the end of the 120-day winter season. (The exact number of days was 119.) The 120 days of winter can be divided into the 60 days of Early Winter ending on the Winter Solstice and the 60 days of Late Winter following the Solstice.

The Kanayama blogsite has posted two photos taken on 2018.02.19 at 13:23 and 13:33. Note how well the lower edge of the spotlight matches the edge of the Sekimen. Comparison of the two photos shows that the solar altitude has decreased during the ten minutes lapse, causing the spotlight to move higher “up” the stone face. The spotlight of 2/19 matches that of 10/23, because the sun’s altitude is the same on these two days.

Here is a view of the beam of light entering from the crevice above. Three megaliths form the crevice and shape the sunbeam in exactly the right way.

It is lovely at Kanayama Megaliths. Chika-san visited on the spring cross-quarter date (half-angle date of the Kanayama solar calendar) , April 22, 2017. In addition to photographing solar phenomena, she took these pictures of spring in Iwaya Valley.

The first three photos are the sakura and pink peach blossoms growing by the side of the road. Notice how petals drift down in the breeze and form a pink river on the ground.

The fourth photo is that of Monotropastrum globosum or Monotropastrum humile (銀龍草: ギンリョウソウ ginryousou). Monotropastrum humile is a species of myco-heterotrophic plant of the family Ericaceae, distributed throughout eastern Asia. It lacks chlorophyll and is therefore unable to photosynthesis as most plants do; instead it gains sugars and nutrients from mycorrhizal fungi. (Wikipedia). Monotropastrum humile (D.Don) H.Hara is the accepted name of a species in the genus Monotropastrum (family Ericaceae). You can read about it here.
