Acer griseum (Franch.) Pax, Pflanzenr. IV, 163: 30 1902. (syn: Acer nikoense var. griseum Franch.; Acer pedunculatum K.S.Hao; Crula grisea Nieuwl.);

Acer griseum (paperbark maple; simplified Chinese: 血皮枫; traditional Chinese: 血皮楓; pinyin: xuè pí fēng) is a species of flowering plant in the family Sapindaceae, native to central China.

It is a small to medium-sized deciduous tree, reaching 6–9 m (20–30 ft) tall and 5–6 m (16–20 ft) wide, with a trunk up to 70 cm (28 in) in diameter.[3] The bark is smooth, shiny orange-red, peeling in thin, papery layers; it may become fissured in old trees. The shoots are densely downy at first, this wearing off by the second or third year and the bark exfoliating by the third or fourth year. The leaves are compound, with a 2–4 cm petiole with three leaflets, each 3-10 cm long and 2-6 cm broad, dark green above, bright glaucous blue-green beneath, with several blunt teeth on the margins. The yellow flowers are androdioecious, produced in small pendent corymbs in spring, the fruit being a paired samara with two winged seeds about 1 cm long with a 3 cm wing.
Acer griseum is found in the Chinese provinces of Gansu, Henan, Hubei, Hunan, Shaanxi, Shanxi and Sichuan, at altitudes of 1,500–2,000 m (4,921–6,562 ft).[2]
Acer griseum was introduced to cultivation in Europe in 1901 by Ernest Henry Wilson for the Veitch Nurseries, and to North America shortly after. It is one of many species of maples widely grown as ornamental plants in temperate regions. It is admired for its decorative exfoliating bark, translucent pieces of which often stay attached to the branches until worn away. It also has spectacular autumn foliage which can include red, orange and pink tones.

Sorry for the bad picture quality due to cloudy weather.

acer griseum

if you had changed your white balance to cloudy or even sunset… and gone to scene or even beech mode …
this problem could have been avoided esp in scene mode

Thanks for confirming the id.
Next time, I will remember to change the settings.
During this visit, it was just running from one tree to another.
