Alturlie Point and the Alturlie Gravels Formation
Alturlie Point is formed of a series of roughly east
-
west
-
orientated ridges that reach a
maximum elevation of about 31 m OD (Firth, 1984
, Merritt, 1990
). The promontory
offers
a good viewpoint from which to consider the evidence of relative sea
-
level
change around the Inverness Firth in general
(Merritt et al., 2017)
, and it contains
morphological evidence for shorelines at 29.3, 23.2, 16.6, 14.7 and 11.8 m OD (Firth,
1989a) (Fi
g. 20 & 21). It is the type area of the
Bothyhill Gravels Member
of the
Alturlie
Gravels Formation
(Merritt et al., 1995), which stretches eastwards from Alturlie Point
within the ‘marine Limit’ (Fig. 14). The kettled spread is generally lower
-
lying than t
he
peninsula because it remained either beneath glacier ice, or sediment containing
buried ice
-
masses, until relative sea level had fallen, possible to below 13 m OD (Firth,
1984) (Fig. 22). Although many of the sections in Bothyhill Pit [NH 715 491] (AP2)
have degraded since being described by Merritt et al. (1995) and Fletcher et al. (1996),
lower parts of the sequence were still exposed in 2017 and new exposures may
become availabl
The Beum a’ Chlaidheimh Breach and the Dulnain-Findhorn divide
The localities described in this section are pertinent to understanding the regional
history of glaciation and deglaciation
(Merritt et al., 2017)
. The landscape may be
viewed from various passing places along the B9007 road linking Duthill and
Lochindorb, but longer walks are recommended across rough ground to see specific
features to the west and east of the highest section of the road at the
Beum

The Allt Odhar (Moy) Interstadial site
The
Allt Odhar
site [NH 798 368] lies at c. 371 m OD on the Moy Estate, some 16 km
south
-
east of Inverness (Fig. 100). Preserved within a sequence of glacial deposits,
there is a notable bed of compressed peat containing pollen, insect remains and plant
macrofossils (Me
rritt, 1990b
,
1993
). Analysis of pollen, plant
-
macrofossil and beetle
remains has allowed a detailed reconstruction of environmental conditions during an
Early Devensian interstadial. The close proximity (9 km) of this site to
Dalcharn
is of
significance be
cause they are the first sites from the mainland of Scotland to provide
evidence of wooded conditions during both an interstadial and an interglacial period
of the Middle or Late Quaternary. The deposits also have significant potential for
establishing a d
etailed glacial history of the area

Keynote: Jon Gertner
The symposium will start on the evening of April 16 with a keynote address by Jon Gertner. Jon is a journalist, historian, and feature writer for The New York Times Magazine
as well as the author of the NYTimes bestseller, The Idea Factory. His address will focus on the issue of intellectual property and the ethical questions around the huge amount of human-generated content that large language models use as they are developed
An introduction to the Quaternary geology and geomorphology of the area around Fort Augustus, Great Glen
Fort Augustus lies within the Great Glen at the south-western end of Loch Ness (Merritt et
al., 2013, fig.17). The settlement straddles the Caledonian Canal, which follows the valley of
the River Oich south-westwards towards Loch Oich and, eventually, Fort William. The
landforms and deposits in the vicinity of Fort Augustus include drift limits, kame-and-kettle
topography and raised lake shorelines. They provide important information for interpreting
events that occurred during late-glacial times, in particular, evidence for re-depression of the
Earth's crust by the build-up of ice in the western Highlands during the Loch Lomond Stadial
(LLS) (Firth, 1986, 1989), and for catastrophic drainage of the former ice-dammed lake in
Glen Spean and Glen Roy, some 30 km to the south-west, towards the end of the Stadial
(Sissons, 1979a, 1981). Three sites are described here; Borlum (NH 384 084), the ‘north
shore’ of Loch Ness (NH 386 105) and Auchteraw (NH 364 082) (Fig. 1). A summary of
each site is given below together with some new information obtained from a recent
geological survey of the district (BGS, 2012). All modern BGS mapping around Fort
Augustus is available digitally or as paper maps at the 1:10,000 scale
Jon Mirande eta ironia
La ironía es un elemento que ha ido siempre unido a la poesía, y especialmente a la poesía moderna.Tras un pequeño repaso a esta en diferentes épocas, se pasa a describir las tres diferentes ironías de Jon Mirande: la intelectual, la social y la filosófica. Todo ello acompañado de ejemplosIrony is an element that has always been united to poetry, and especially to modern poetry. After a small revision of irony in different eras, the author then describes the three different ironies of Jon Mirande: intellectual, social and philosophical irony. All this illustrated with example
Ardersier Peninsula and the Ardersier Silts Formation
T
he Ardersier Peninsula is formed mainly of rhythmically bedded silts and
sands of probable glaciomarine origin (
Ardersier Silts Fm
), locally capped
by till, and trimmed on the north and west sides by Late Devensian (late
-
glacial) and Holocene (postglacial or Flandrian) raised shorelines. The
peninsula rises to an altitude of about 40 m OD, but the highest marine
features are shingle ridges at 28
-31 m OD, below which lie late
-glacial
shoreline fragments at altitudes of 28.5 m, 26.6 m, 21
-21.6 m and 18.5 m
OD (Firth, 1984, 1989b) (Fig. 30). The prominent ‘Main Postglacial
Cliffline’ borders raised shingle beach ridges at about 11 m OD (see cover
photo). This prominent abandoned cliff
line was generally thought to
have been created by marine erosion
during the Holocene, but it is now
considered to have been formed mainly in the cold climate of the Loch
Lomond Stadial (Younger Dryas) and that the feature was only trimmed
during the mid
- Holocene
( Sissons, 1981a). The peninsula includes
important evide
nce for a significant glacial readvance within the
Inverness Firth, termed the
Ardersier Readvance
by J.S. Smith (1968,
1977) or the
Ardersier Oscillation
by Merritt et al. (1995)

An overview of the main Late Devensian glaciation of the Central Grampian Highlands
The location of the Monadhliath Mountains in the middle of the Grampian Highlands
places them in a central zone with respect to ice flow pathways during the maximum
extent of the last British and Irish Ice Sheet (BIIS) in the Late Devensian. At the ice
sheet maximum the Scottish mainland was probably entirely submerged beneath ice,
which flowed north-westwards out to the continental shelf break, merging with
Scandinavian ice occupying the North Sea basin (Bradwell et al., 2008). This period
roughly equates with the global Last Glacial Maximum (LGM), 28,000-22,000 years
ago (Mix et al. 2001). The most recent model of the BIIS (Clark et al., 2012) places
the Monadhliath Mountains immediately to the east of the main north-south ice divide
of the Scottish ice sheet, and north of a subsidiary west-east divide, centred over the
East Grampian and Cairngorm mountains. Geomorphological evidence for ice
streaming in the Great Glen and Spey Valley to the northeast and southwest of the
Monadhliath massif indicates a general ice flow direction towards the northeast across
the region, supporting this ice-divide positioning
