Plant of the Day

Tuesday 21 October 2025

In the landscaping of this public space a small tree had been included, Sorbus ‘Flanrock’ (rowan, mountain ash, Autumn Spire), this has a columnar habit. The foliage turns purple, red and yellow in the autumn which contrasts with the masses of yellow berries with red centres that follow the white flowers of summer.

Harpa Concert Hall: from nature to architecture

The building stands out like a vast, dazzling sculpture on the edge of land and sea, reflecting both sky and harbor space as well as the active lifestyle of the city.

The building stands out like a vast, dazzling sculpture on the edge of land and sea, reflecting both sky and harbor space as well as the active lifestyle of the city. Henning Larsen Architects, the Danish-Icelandic artist Olafur Eliasson, and the German engineering firms Rambll and ArtEngineering GmbH collaborated closely to create the outstanding façades.

Harpa means ‘harp’ in Icelandic. It is also the Icelandic name for the first month of spring, and thus a sign of brighter times. Today, the most visited attraction of the volcanic island carries the name – Harpa. Between a rock-solid core and a crystalline shell, everyday life unfolds in the expansive foyer – where a varied mix of playing children, yoga classes, concert guests, and international conference delegates have embraced the space altogether. — Henning Larsen

The project was the winner of the prestigious European Union Prize for Contemporary Architecture: Mies van der Rohe, in 2013. Its geometric façade is based on a modular, space-filling construction termed the quasi brick, which is reminiscent of the crystalline basalt columns typical in Iceland. The pseudo brick modules include color-effect filter glass panes; the structure shimmers in response to the weather, time of year or day, and the position and motions of spectators.

Inside the plumbing system of an ancient volcano

A fossil plumbing system of an ancient Waitakere Volcano. Though the volcano went extinct and was largely eroded away, the lava flows that once spew from it are now preserved along the Maori Bay coast. The radial feature is an internal view of lava flow lobe that shows rosette style columnar jointing. This feature forms when large lava flow moves and cools slowly, allowing columns to grow, which at the same time are bent due to ongoing lava movement.

Muriwai, New Zealand

A detailed description of this flow is available in the following article:

Bear, A.N. and Cas, R.A.F., 2007. The complex facies architecture and emplacement sequence of a Miocene submarine mega-pillow lava flow system, Muriwai, North Island, New Zealand. Journal of volcanology and geothermal research, 160(1-2), pp. 1-22.

Landscape Language

Geologic Joint (noun) – a fracture in a rock

Rocks often fracture creating joints. A common type of joint found in the park is columnar jointing, when lava fractures into a series of columns as it cools into rock. There are many different types of joints, and they can extend for miles in complicated systems. The type of joint can provide clues as to how a rock formed, and can affect how it weathers or breaks down in the future. Have you seen columnar jointing or other joint examples in the park? ___________ NPS Photo of a rock feature with numerous joints along the Palisades Lake Trail. Description: A rocky cliff built of layers of rocks broken into rough columns. ~kl
